Siddharth Seth updated TEZ-1095:
--------------------------------
Target Version/s: 0.7.0
> Enable tez.runtime.shuffle.memory-to-memory.enable for mem-to-mem merging
> -------------------------------------------------------------------------
>
> Key: TEZ-1095
> URL: https://issues.apache.org/jira/browse/TEZ-1095
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Rajesh Balamohan
>
> Currently tez.runtime.shuffle.memory-to-memory.enable is set to false by
> default. We need to evaluate the usefulness of this parameter and enable it
> by default if it provides good perf boosts.
> There is also a possibility that waitForInMemoryMerge() will return in sub
> milliseconds when this parameter is enabled, causing pressure on network
> resources. Related JIRA: https://issues.apache.org/jira/browse/TEZ-1091
