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

注：php版本要求是5.2或者以上

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 Hiverequire_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/
