> 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),
