Review request for Ambari and Myroslav Papirkovskyy.
Bugs: AMBARI-9064
https://issues.apache.org/jira/browse/AMBARI-9064
Repository: ambari
Description
-------
we need to change the nm retry settings to resolve the bug. The proposed new
settings in yarn-site.xml are:
yarn.client.nodemanager-connect.max-wait-ms = 60,000
yarn.client.nodemanager-connect.retry-interval-ms = 10,000
If the underlying rpc retry takes 1 sec * 50 times to finish (50 secs), this
will make each round of retry to be 10 + 50 secs = 1 minute. From the code,
there will be 60,000 / 10,000 = 6 times of retries. So, in total, if the node
manager accidentally crashed and never goes up, we well retry 1 minute * 6
times = 6 minutes. The whole calculation is based on the rpc settings (50
times, 1 sec sleep time),
