您当前的位置: 参考官方文档：http://gora.apache.org/current/tutorial.html
项目代码见：https://code.csdn.net/jediael_lu/mygorademo
一、环境准备
1、下载gora并解压
2、分别进入$GORA_HOME/gora-hbase/，$GORA_HOME/gora-core，$GORA_HOME/gora-compiler，$GORA_HOME/gora-compiler-CLI执行
$ mvn clean install
或者直接在$GORA_HOME执行此命令。
3、启动hbase，需要有zookeeper，即一般为分布式的hbase。
注意gora-0.5对应Hbase0.94
4、准备好日志文件，用于本项目的分析
二、建立项目
1、建立一个java project
（1）创建以下几个目录
（2）构建build path，增加hadoop library,hbase library以及avro, gora相关的类包，详见后面的项目结构。
（3）将准备好的日志文件放到resource目录下
2、在conf目录下创建gora.properties，内容如下：
##gora.datastore.default is the default detastore implementation to use ##if it is not passed to the DataStoreFactory#createDataStore() method. gora.datastore.default=org.apache.gora.hbase.store.HBaseStore #gora.datastore.default=org.apache.gora.cassandra.store.CassandraStore #gora.datastore.default=org.apache.gora.solr.store.SolrStore #gora.datastore.default=org.apache.gora.avro.store.AvroStore #gora.avrostore.input.path=hdfs://localhost:9000/gora.avrostore.test.input #gora.avrostore.output.path=hdfs://localhost:9000/gora.avrostore.test.output #gora.avrostore.codec.type=JSON || BINARY ##whether to create schema automatically if not exists. gora.datastore.autocreateschema=true ##Cassandra properties for gora-cassandra module using Cassandra #gora.cassandrastore.servers=localhost:9160 ##JDBC properties for gora-sql module using HSQL gora.sqlstore.jdbc.driver=org.hsqldb.jdbcDriver ##HSQL jdbc connection as persistent in-process database gora.sqlstore.jdbc.url=jdbc:hsqldb:file:./hsql-data ##HSQL jdbc connection as network server #gora.sqlstore.jdbc.url=jdbc:hsqldb:hsql://localhost/goratest ##JDBC properties for gora-sql module using MySQL #gora.sqlstore.jdbc.driver=com.mysql.jdbc.Driver #gora.sqlstore.jdbc.url=jdbc:mysql://localhost:3306/goratest #gora.sqlstore.jdbc.user=root #gora.sqlstore.jdbc.password= gora.solrstore.solr.url=http://localhost:8983/solr gora.solrstore.solr.commitwithin=0 gora.solrstore.solr.batchsize=100 # set which Solrj server impl you wish to use # cloud, concurrent, http, loadbalance gora.solrstore.solr.solrjserver=http
3、在avro目录下创建pageview.json，内容如下：
{
"type": "record",
"name": "Pageview", "default":null,
"namespace": "org.apache.gora.tutorial.log.generated",
"fields" : [
{"name": "url", "type": ["null","string"], "default":null},
{"name": "timestamp", "type": "long", "default":0},
{"name": "ip", "type": ["null","string"], "default":null},
{"name": "httpMethod", "type": ["null","string"], "default":null},
{"name": "httpStatusCode", "type": "int", "default":0},
{"name": "responseSize", "type": "int", "default":0},
{"name": "referrer", "type": ["null","string"], "default":null},
{"name": "userAgent", "type": ["null","string"], "default":null}
]
}
4、根据pageview.json生成java类
$ pwd
/Users/liaoliuqing/99_Project/1_myCodes/MyGoraDemo
$ gora goracompiler avro/pageview.json src/
Compiling: /Users/liaoliuqing/99_Project/1_myCodes/MyGoraDemo/avro/pageview.json
Compiled into: /Users/liaoliuqing/99_Project/1_myCodes/MyGoraDemo/src
Compiler executed SUCCESSFULL.
此命令在src目录下生成一个类：
org.apache.gora.tutorial.log.generated.Pageview.java
生成的内容请见最后面。
5、创建gora-hbase-mapping.xml，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!--
Gora Mapping file for HBase Backend
-->
<gora-otd>
<table name="Pageview"> <!-- optional descriptors for tables -->
<family name="common"/> <!-- This can also have params like compression, bloom filters -->
<family name="http"/>
<family name="misc"/>
</table>
<class name="org.apache.gora.tutorial.log.generated.Pageview" keyClass="java.lang.Long" table="AccessLog">
<field name="url" family="common" qualifier="url"/>
<field name="timestamp" family="common" qualifier="timestamp"/>
<field name="ip" family="common" qualifier="ip" />
<field name="httpMethod" family="http" qualifier="httpMethod"/>
<field name="httpStatusCode" family="http" qualifier="httpStatusCode"/>
<field name="responseSize" family="http" qualifier="responseSize"/>
<field name="referrer" family="misc" qualifier="referrer"/>
<field name="userAgent" family="misc" qualifier="userAgent"/>
</class>
<class name="org.apache.gora.tutorial.log.generated.MetricDatum" keyClass="java.lang.String" table="Metrics">
<field name="metricDimension" family="common" qualifier="metricDimension"/>
<field name="timestamp" family="common" qualifier="ts"/>
<field name="metric" family="common" qualifier="metric"/>
</class>
</gora-otd>

四、程序分析
1、项目结构
2、数据库的其它操作（读取与删除）请参考官方文档。
以下为部分内容的截取，更详细内容请见http://gora.apache.org/current/tutorial.html
Fetching objects from data store
Fetching objects from the data store is as easy as storing them. There are essentially two methods for fetching objects. First one is to fetch a single object given it's key. The second method is to run a query through the data store.
To fetch objects one by one, we can use one of the overloaded get() methods. The method with signature get(K key) returns the object corresponding to the given key fetching all the fields. On the other hand get(K key, String[] fields) returns the object corresponding
to the given key, but fetching only the fields given as the second argument.
When run with the argument -get LogManager class fetches the pageview object from the data store and prints the results.
/** Fetches a single pageview object and prints it*/
private void get(long key) throws IOException {
Pageview pageview = dataStore.get(key);
printPageview(pageview);
}
To display the 42nd line of the access log :
$ bin/gora logmanager -get 42
org.apache.gora.tutorial.log.generated.Pageview@321ce053 {
"url":"/index.php?i=0&a=1__rntjt9z0q9w&k=398179"
"timestamp":"1236710649000"
"ip":"88.240.129.183"
"httpMethod":"GET"
"httpStatusCode":"200"
"responseSize":"43"
"referrer":"http://www.buldinle.com/index.php?i=0&a=1__RnTjT9z0Q9w&k=398179"
"userAgent":"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"
}
Querying objects
DataStore API defines a Query interface to query the objects at the data store. Each data store implementation can use a specific implementation of the Query interface. Queries are instantiated by calling DataStore#newQuery(). When the query is run through
the datastore, the results are returned via the Result interface. Let's see how we can run a query and display the results below in the the LogManager class.
/** Queries and prints pageview object that have keys between startKey and endKey*/
private void query(long startKey, long endKey) throws IOException {
Query<Long, Pageview> query = dataStore.newQuery();
//set the properties of query
query.setStartKey(startKey);
query.setEndKey(endKey);
Result<Long, Pageview> result = query.execute();
printResult(result);
}
After constructing a Query, its properties are set via the setter methods. Then calling query.execute() returns the Result object.
Result interface allows us to iterate the results one by one by calling the next() method. The getKey() method returns the current key and get() returns current persistent object.
private void printResult(Result<Long, Pageview> result) throws IOException {
while(result.next()) { //advances the Result object and breaks if at end
long resultKey = result.getKey(); //obtain current key
Pageview resultPageview = result.get(); //obtain current value object
//print the results
System.out.println(resultKey + ":");
printPageview(resultPageview);
}
System.out.println("Number of pageviews from the query:" + result.getOffset());
}
With these functions defined, we can run the Log Manager class, to query the access logs at HBase. For example, to display the log records between lines 10 and 12 we can use:
bin/gora logmanager -query 10 12
Which results in:
10:
org.apache.gora.tutorial.log.generated.Pageview@d38d0eaa {
"url":"/"
"timestamp":"1236710442000"
"ip":"144.122.180.55"
"httpMethod":"GET"
"httpStatusCode":"200"
"responseSize":"43"
"referrer":"http://buldinle.com/"
"userAgent":"Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.6) Gecko/2009020911 Ubuntu/8.10 (intrepid) Firefox/3.0.6"
}
11:
org.apache.gora.tutorial.log.generated.Pageview@b513110a {
"url":"/index.php?i=7&a=1__gefuumyhl5c&k=5143555"
"timestamp":"1236710453000"
"ip":"85.100.75.104"
"httpMethod":"GET"
"httpStatusCode":"200"
"responseSize":"43"
"referrer":"http://www.buldinle.com/index.php?i=7&a=1__GeFUuMyHl5c&k=5143555"
"userAgent":"Mozilla/5.0 (Windows; U; Windows NT 5.1; tr; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7"
}
Deleting objects
Just like fetching objects, there are two main methods to delete objects from the data store. The first one is to delete objects one by one using the DataStore#delete(K key) method, which takes the key of the object. Alternatively we can delete all of the data
that matches a given query by calling the DataStore#deleteByQuery(Query query) method. By using #deleteByQuery, we can do fine-grain deletes, for example deleting just a specific field from several records. Continueing from the LogManager class, the api's
for both are given below.
/**Deletes the pageview with the given line number */
private void delete(long lineNum) throws Exception {
dataStore.delete(lineNum);
dataStore.flush(); //write changes may need to be flushed before they are committed
}
/** This method illustrates delete by query call */
private void deleteByQuery(long startKey, long endKey) throws IOException {
//Constructs a query from the dataStore. The matching rows to this query will be deleted
Query<Long, Pageview> query = dataStore.newQuery();
//set the properties of query
query.setStartKey(startKey);
query.setEndKey(endKey);
dataStore.deleteByQuery(query);
}
And from the command line :
bin/gora logmanager -delete 12
bin/gora logmanager -deleteByQuery 40 50
- See more at: http://gora.apache.org/current/tutorial.html#sthash.i7gfQUe7.dpufFetching objects from the data store is as easy as storing them. There are essentially two methods for fetching objects. First one is to fetch a single object given it's key. The
second method is to run a query through the data store.
