php通过thrift操作hbase

环境配置 

操作系统 centos 5.8    hadoop版本cloudera cdh3u3  hbase版本hbase-0.90.4-cdh3u3  php版本5.2

1.  下载并编译thrift

     # wget http://ftp.tc.edu.tw/pub/Apache/thrift/0.8.0/thrift-0.8.0.tar.gz

     安装所需的依赖包

     # yum install automake libtool flex bison pkgconfig gcc-c++ boost-devel libevent-devel zlib-devel python-devel ruby-devel php php-devel

   # tar zxvf  thrift-0.8.0.tar.gz

     # cd thrift-0.8.0

    #   ./configure --prefix=/home/thrift --with-php-config=/usr/bin/php-config

  # make && make install

2  生成php和hbase的接口文件：

    # cd /home/thrift/

   # bin/thrift  --gen php $HBASE_HOME/src/main/resources/org/apache/hadoop/hbase/thrift/Hbase.thrift

  # cd gen-php/Hbase

  # ls

Hbase.php  Hbase_types.php

3. 把PHP客户端需要的包及刚才生成的接口文件复制出来供php程序调用：

#  mkdir -p  /var/www/html/hbasethrift/libs     (/var/www/html为apache的web主目录)

#  cp -a /home/soft/thrift-0.8.0/lib/php/src /var/www/html/hbasethrift/libs     

#  mkdir -p /var/www/html/hbasethrift/libs/packages

#  cp -a /home/thrift/gen-php/Hbase /var/www/html/hbasethrift/libs/packages

4.  启动hbase thrift server，测试php连接hbase

  # ./bin/hbase-daemon.sh start thrift  

 hbase thrift 默认监听端口为9090

测试php连接与操作hbase代码 

# vi hbasethrift.php

<?php$GLOBALS['THRIFT_ROOT'] = '/home/www/html/hbasethrift/libs';require_once( $GLOBALS['THRIFT_ROOT'].'/Thrift.php' );require_once( $GLOBALS['THRIFT_ROOT'].'/transport/TSocket.php' );require_once( $GLOBALS['THRIFT_ROOT'].'/transport/TBufferedTransport.php' );require_once( $GLOBALS['THRIFT_ROOT'].'/protocol/TBinaryProtocol.php' );require_once( $GLOBALS['THRIFT_ROOT'].'/packages/Hbase/Hbase.php' );$socket = new TSocket( 'localhost', 9090 );$socket->setSendTimeout( 10000 ); // Ten seconds (too long for production, but this is just a demo ;)$socket->setRecvTimeout( 20000 ); // Twenty seconds$transport = new TBufferedTransport( $socket );$protocol = new TBinaryProtocol( $transport );$client = new HbaseClient( $protocol );$transport->open();echo nl2br( "listing tables...\n" );$tables = $client->getTableNames();sort( $tables );foreach ( $tables as $name ) {echo nl2br( "  found: {$name}\n" );}$columns = array(new ColumnDescriptor( array('name' => 'entry:','maxVersions' => 10) ),new ColumnDescriptor( array('name' => 'unused:') ));$t = "table1";echo( "creating table: {$t}\n" );try {$client->createTable( $t, $columns );} catch ( AlreadyExists $ae ) {echo( "WARN: {$ae->message}\n" );}$t = "test";echo( "column families in {$t}:\n" );$descriptors = $client->getColumnDescriptors( $t );asort( $descriptors );foreach ( $descriptors as $col ) {echo( "  column: {$col->name}, maxVer: {$col->maxVersions}\n" );}$t = "table1";echo( "column families in {$t}:\n" );$descriptors = $client->getColumnDescriptors( $t );asort( $descriptors );foreach ( $descriptors as $col ) {echo( "  column: {$col->name}, maxVer: {$col->maxVersions}\n" );}$t = "table1";$row = "row_name";$valid = "foobar-\xE7\x94\x9F\xE3\x83\x93";$mutations = array(new Mutation( array('column' => 'entry:foo','value' => $valid) ),);$client->mutateRow( $t, $row, $mutations );$table_name = "table1";$row_name = 'row_name';$fam_col_name = 'entry:foo';$arr = $client->get($table_name, $row_name , $fam_col_name);// $arr = arrayforeach ( $arr as $k=>$v  ) {// $k = TCellecho ("value = {$v->value} , <br>  ");echo ("timestamp = {$v->timestamp}  <br>");}$table_name = "table1";$row_name = "row_name";$arr = $client->getRow($table_name, $row_name);// $client->getRow return a arrayforeach ( $arr as $k=>$TRowResult  ) {// $k = 0 ; non-use// $TRowResult = TRowResultvar_dump($TRowResult);}$transport->close();?>

通过浏览器访问http://localhost/hbasethrift/hbasethrift.php,如果显示hbase中的表名与新建表table1 ，说明连接成功。
