Subject Re: ClassCastExceptions using Hiveserver2 Thrift interface, Hive 0.11
Date Mon, 21 Oct 2013 09:56:15 GMT
I can report I see this same error when working with the Perl thrift Hive
client (
http://search.cpan.org/~dmor/Thrift-API-HiveClient2-0.011/lib/Thrift/API/HiveClient2.pm),
and with the newly released Hive 0.12.0.

Is anyone successfully using Hiveserver2, or do I have something odd in my
environment?
