Junping Du created MAPREDUCE-6164:
-------------------------------------
Summary: "mapreduce.reduce.shuffle.fetch.retry.timeout-ms" should
be set to 3 minutes instead of 30 seconds by default to keep insistent with
other retry timeout
Key: MAPREDUCE-6164
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6164
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Junping Du
Assignee: Junping Du
In MAPREDUCE-5891, we are adding retry logic to MAPREDUCE shuffle stage for
fetcher can be survival during NM downtime (with shuffle service down as well).
In many places, we are setting the default timeout to be 3 minutes (connection
timeout, etc.) to tolerant possible more time for NM down, but we are making
"mapreduce.reduce.shuffle.fetch.retry.timeout-ms" to be 30 seconds which is not
consistent here. We should change this to 180 seconds.
