使用php连接hive的条件

1  需要安装thrift  安装步骤

#  ./configure --without-ruby 

#   make && make install

如果没有安装libevent libevent-devel的应该先安装这两个依赖库yum -y install libevent libevent-devel

安装好后启动hive thrift

# ./hive --service hiveserver >/dev/null 2>/dev/null &

查看hiveserver默认端口是否打开10000   如果打开表示成功

php连接hive代码

<? // php连接hive thrift依赖包路径 $GLOBALS['THRIFT_ROOT'] = '/var/www/html/hivephp/thrift/'; // load the required files for connecting to Hive require_once $GLOBALS['THRIFT_ROOT'] . 'packages/hive_service/ThriftHive.php'; require_once $GLOBALS['THRIFT_ROOT'] . 'transport/TSocket.php'; require_once $GLOBALS['THRIFT_ROOT'] . 'protocol/TBinaryProtocol.php'; // Set up the transport/protocol/client $transport = new TSocket('localhost', 10000); $protocol = new TBinaryProtocol($transport); $client = new ThriftHiveClient($protocol); $transport->open(); // run queries, metadata calls etc $client->execute('add jar /usr/local/hadoop/hive/lib/hive-contrib-0.7.0-cdh3u0.jar'); $client->execute('select count(1) from apilog'); var_dump($client->fetchAll()); $transport->close(); ?>

将以上代码存为test.php到apache的www路径/var/www/html/中  php连接hive的依赖包放到/var/www/html/hivephp/thrift/
