Subject Re: Thrift Java Client - TTransportException (SocketException: Connection reset)
Date Fri, 25 Feb 2011 07:21:55 GMT
Hi Ayush,

I suspect you're running into Thrift's default socket timeout setting. I
recommend checking out a copy of the Hive source code, and modifying the
Thrift setup code in HiveServer.java to explicitly set the socket timeout on
the TServerSocket, e.g. in HiveServer.main() change

TServerTransport serverTransport = new TServerSocket(port);

to

TServerTransport serverTransport = new TServerSocket(port, timeout);

The Thrift javadoc doesn't specify whether timeout is in seconds or
milliseconds, so you'll probably have to play around with this value.

Hope this helps.

Carl
