[jira] [Created] (YARN-5718) TimelineClient (and other places in
YARN) shouldn't over-write HDFS client retry settings which could cause
unexpected behavior
Junping Du created YARN-5718:
--------------------------------
Summary: TimelineClient (and other places in YARN) shouldn't over-write HDFS client retry settings which could cause unexpected behavior
Key: YARN-5718
URL: https://issues.apache.org/jira/browse/YARN-5718
Project: Hadoop YARN
Issue Type: Bug
Components: timelineclient, resourcemanager
Reporter: Junping Du
Assignee: 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.
