----------------------------------
Thanks Junping, the updated patch looks good.
Not sure what the compilation error is:
{code}
[ERROR] COMPILATION ERROR :

Perhaps unrelated.

> URL: https://issues.apache.org/jira/browse/YARN-5718
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager, timelineclient
> Reporter: Junping Du

>
> In one HA cluster, after NN failed over, we noticed that job is getting
> failed as TimelineClient failed to retry connection to proper NN. This is
> because we are overwrite hdfs client settings that hard code retry policy to
> be enabled that conflict NN failed-over case - hdfs client should fail fast
> so can retry on another NN.
> We shouldn't assume any retry policy for hdfs client at all places in YARN.
> This should keep consistent with HDFS settings that has different retry
> polices in different deployment case. Thus, we should clean up these hard
> code settings in YARN, include: FileSystemTimelineWriter,
> FileSystemRMStateStore and FileSystemNodeLabelsStore.
