Question

我想从php客户端连接到hiveserver2。但是，我得到一个空白页面（我应该在蜂巢中看到一个表格列表）。我修改了代码 https://github.com/garamon/php-thrift-hive-client。最初，我收到了这个错误 TSocket: timed out reading 4 bytes from host。按照此处https://stackoverflow.com/a/19199938/4379550建议实施补丁后。错误消失但我什么都没得到。我的代码如下

<?php
$GLOBALS['THRIFT_ROOT'] = dirname(__FILE__) . '/lib';
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';

require_once dirname(__FILE__) . '/ThriftHiveClientEx.php';

$transport = new TSocket('hadoop-gate.iis.u-tokyo.ac.jp', 10000);
$transport->setSendTimeout(600 * 100);
$transport->setRecvTimeout(600 * 100);
$client = new ThriftHiveClientEx(new TBinaryProtocol($transport));
$client->open();

//show tables
$client->execute('SHOW TABLES');
print_r($client);
$tables = $client->fetchAll();
print_r($tables);
foreach ($tables as $name){
  echo( " found: {$name}\n" );
}
?>

从cloudera manager检索到的服务器上的错误消息如下所示：

6:49:48.859 PM  ERROR   org.apache.thrift.server.TThreadPoolServer

我将不胜感激任何帮助。非常感谢提前。

对于那些面临同样问题的人，我通过设置hive.server2.authentication解决了这个问题之前已回复here的NOSASL财产。我之前无法完成它的原因是因为我正在改变这个属性在服务器上的文件并没有用，我猜是因为我正在使用cloudera发行版。有用的是在cloudera manager中设置此属性，如documentation中所述。
