Hello [~piaoyu zhang] thanks for reporting this jira.
Do you have more information regarding this finding? For instance, stack trace that shows
a thread is stuck in this call?

Without more information it would be hard to tell what happened here exactly. If I were to
guess, was the file being closed in a snapshottable directory?

Also, your reported environment is on Hadoop 2.2. A lot have changed since Hadoop 2.2, do
you think the issue still applies to more recent versions?
