> Log longest FSN write/read lock held stack trace

> Key: HDFS-13946
> URL: https://issues.apache.org/jira/browse/HDFS-13946
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.1.1
> Reporter: Yiqun Lin
> Assignee: Yiqun Lin
> Priority: Minor
> Attachments: HDFS-13946.001.patch

>
> FSN write/read lock log statement only prints longest lock held interval not
> its stack trace during suppress warning interval. Only current thread is
> printed, but it looks not so useful. Once NN is slowing down, the most
> important thing we take care is that which operation holds longest time of
> the lock.
> Following is log printed based on current logic.
