Subject RE: BulkOutputFormat error - org.apache.thrift.transport.TTransportException
Date Wed, 19 Dec 2012 19:07:32 GMT
The problem was with the compatibility. I was using a lower version of Cassandra jar files.
Now, BulkOutputFormat works fine.

Both the rpc_address in caasandra.yaml file and job configuration are same (localhost).
I will try connecting to a different Cassandra cluster and test it again.

Looks like it cannot connect to the server

Is this the same address as the rpc_address in the cassandra config ?
