Cassandra / Hector Timeouts = What to do?

i would be thankfull if a sophisticated user could name all possible solutions (best practices) how to fix Hector Client Timeouts like this:

Caused by:开发者_StackOverflow me.prettyprint.hector.api.exceptions.HTimedOutException: TimedOutException()


Caused by: TimedOutException()

HECTOR:

Taken from the Hector Documentation :https://github.com/rantav/hector/wiki/User-Guide

I found the following related to timeouts:

1.) cassandraThriftSocketTimeout

CASSANDRA:

1.) rpc_timeout_in_ms: 10000 (in cassandra.yaml)

What other Settings are available related to timeouts both on Hector and on Cassandra side? I have time! So I simply want to wait longer! But I have not found the settings therefor to wait longer.

Thanks Markus

From the cassandra.thrift API in the Apache Cassandra source tree regarding TimeoutException:

"RPC timeout was exceeded. either a node failed mid-operation, or load was too high, or the requested op was too large."

In short you were asking for too much data. What sort of query were you sending? Can you post a code snippet of such?
