JobClient completion poll interval of 5s causes slow tests in local mode
------------------------------------------------------------------------
Key: MAPREDUCE-825
URL: https://issues.apache.org/jira/browse/MAPREDUCE-825
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Aaron Kimball
Assignee: Aaron Kimball
Priority: Minor
The JobClient.NetworkedJob.waitForCompletion() method polls for job completion every 5 seconds.
When running a set of short tests in pseudo-distributed mode, this is unnecessarily slow and
causes lots of wasted time. When bandwidth is not scarce, setting the poll interval to 100
ms results in a 4x speedup in some tests. This interval should be parametrized to allow users
to control the interval for testing purposes.
