> 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.
