Marcos Chioratto Trama commented on CASSANDRA-5604: --------------------------------------------------- The issue causes vnodes * replicas tasks be started for each job, correct? Would be nice if we have a parameter to specify the vnodes / task proportion. Example: Vnodes: 256 (default) Replicas: 3 Tasks started by Pig: 768 With proportion = 3 we would have only 768 / 3 = 256 tasks started, improving the performance. This make sense? > Vnodes decrease Hadoop performances cause it creates too many small splits > -------------------------------------------------------------------------- > > Key: CASSANDRA-5604 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5604 > Project: Cassandra > Issue Type: Bug > Components: Hadoop > Affects Versions: 1.2.4 > Environment: Linux Ubuntu 12.04 LTS x86_64 > Reporter: Cyril Scetbon > Priority: Trivial > -- This message is automatically generated by JIRA.
