Jeremy Hanna commented on CASSANDRA-2052: ----------------------------------------- Based on discussion in IRC, it sounds like we just need to communicate good settings to users for when they're configuring and trying out their cluster. So a combination of batch size and rpc timeout tuning along with potentially separating out the nodes into a virtual datacenter with the network topology strategy so that you don't hit your nodes with batch processing jobs that really need to be responsive for oltp. I can update the docs on the wiki and we should probably update the readme in the various hadoop contrib modules to point to the hadoop support wiki page as well. > Add configurable retry count to Hadoop code > ------------------------------------------- > > Key: CASSANDRA-2052 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2052 > Project: Cassandra > Issue Type: Improvement > Components: Hadoop > Affects Versions: 0.6.9, 0.7.0 > Reporter: Jeremy Hanna > > The Hadoop integration code doesn't do a retry if it times out. Often people > have to tune the batch size and the rpc timeout in order to get it to work. > We should probably have a configurable timeout in there (credit to Jairam - > http://www.mail-archive.com/user@cassandra.apache.org/msg08938.html) so that > it doesn't just fail the job with a timeout exception. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
