      Description

      I'm working with the Hive thrift service and I get the following exception when I execute a SELECT statement:

      PHP Fatal error: Uncaught exception 'TException' with message 'TSocket: timed out reading 4 bytes from localhost:10000' in /root/leap/dev/servers/hive/thriftroot/
      transport/TSocket.php:228
      Stack trace:
      #0 /root/leap/dev/servers/hive/thriftroot/protocol/TBinaryProtocol.php(292): TSocket->readAll(4)
      #1 /root/leap/dev/servers/hive/thriftroot/protocol/TBinaryProtocol.php(184): TBinaryProtocol->readI32(NULL)

      #5

      {main}

      thrown in /root/leap/dev/servers/hive/thriftroot/transport/TSocket.php on line 228

      The script I'm using to cause this is:

      ======================================
      #!/usr/bin/php
      <?php

      $GLOBALS['THRIFT_ROOT'] = 'thriftroot/';

      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';

      $transport = new TSocket('localhost', 10000);
      $protocol = new TBinaryProtocol($transport);
      $client = new ThriftHiveClient($protocol);
      $transport->open();

      try
      {
      $client->execute('DROP TABLE testOverThrift');
      }
      catch (Exception $e)
      {
      error_log("Got exception while trying to drop table: " . $e->getMessage());
      }

      $client->execute('CREATE TABLE testOverThrift (num int)');

      $client->execute('LOAD DATA LOCAL
      INPATH "/root/testdata.txt"
      INTO TABLE testOverThrift');

      $client->execute('SELECT num FROM testOverThrift WHERE num < 5');

      $result = $client->fetchAll();

      var_dump($result);
      ==================================

      I have a patch that fixes the problem that I'll attach. It looks like fetchAll() doesn't know the difference between a timeout and a blocking port.
