Hbase通过thrift这个跨语言的RPC框架提供多语言的调用。
Hbase有两套thrift接口(thrift1和thrift2),但是它们并不兼容。根据官方文档,thrift1很可能被抛弃,本文以thrift2整合为例。
1、访问官网http://thrift.apache.org/download,下载
thrift-0.11.0.exe (生成接口rpc工具,thrift-0.11.0.exe改名thrift.exe,保存在D:/project/thrift/thrift.exe)
thrift-0.11.0.tar.gz(thrift相关库,保存在D:/project/thrift/thrift-0.11.0)
2、访问hbase官网(http://archive.apache.org/dist/hbase/),下载hbase-1.2.6-src.tar.gz
解压保存在D:/project/thrift/hbase-1.2.6
3、生成php接口代码
解压hbase-1.2.6-src.tar.gz,hbase-1.2.6/hbase-thrift/src/main/resources/org/apache/hadoop/hbase文件夹同时存在thrift和thrift2接口描述文件,本文只使用thrift2
在D:/project/thrift目录中输入cmd命令,生成对应php的sdk文件。
thrift -gen php hbase-1.2.6/hbase-thrift/src/main/resources/org/apache/hadoop/hbase/thrift2/hbase.thrift
生成的D:/project/thrift/gen-php目录包含文件:
THBaseService.phpTypes.php
4、要通过thrifc调用hbase,需要先启动hbase的接口服务
$HBASE_HOME/bin/hbase-daemon.sh start thrift2 //启动$HBASE_HOME/bin/hbase-daemon.sh stop thrift2 //停止
5、与yii2整合
在vendor文件夹中新建hbase目录
vendor/hbase/gen-php //复制D:/project/thrift/gen-phpvendor/hbase/php //复制D:/project/thrift/thrift-0.11.0/lib/php
由于thrift2的php不使用Composer,类库命名方式也不完全符合PSR-4标准, 所以本文使用include_path方式来定位并导入类文件。
common/models/HArticle.php
<?phpnamespace common/models;require_once dirname(dirname(__DIR__)).'/vendor/hbase/php/lib/Thrift/ClassLoader/ThriftClassLoader.php';use Thrift/ClassLoader/ThriftClassLoader;$loader = new ThriftClassLoader();$loader->registerNamespace('Thrift', dirname(dirname(__DIR__)) . '/vendor/hbase/php/lib');$loader->register();require_once dirname(dirname(__DIR__)) . '/vendor/hbase/gen-php/Types.php';require_once dirname(dirname(__DIR__)) . '/vendor/hbase/gen-php/THBaseService.php';use Thrift/Protocol/TBinaryProtocol;use Thrift/Transport/TSocket;use Thrift/Transport/TBufferedTransport;use THBaseServiceClient;use TGet;class HArticle{ private $host = '192.168.1.108'; private $port = 9090; public function get($rowKey){ $socket = new TSocket($this->host, $this->port); $transport = new TBufferedTransport($socket); $protocol = new TBinaryProtocol($transport); $client = new THBaseServiceClient($protocol); $transport->open(); $tableName = "article_2018"; $get = new TGet(); $get->row = $rowKey; $arr = $client->get($tableName, $get); $data = array(); $results = $arr->columnValues; foreach($results as $result) { $qualifier = (string)$result->qualifier; $value = $result->value; $data[$qualifier] = $value; } $transport->close(); return $data; }}
