> 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.
