>
> 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.
