> In HBASE-8389, there was discussion for utilizing isFileClosed() to optimize the wait
time for lease recovery.
> Subsequent lease recovery request for the same Path would preempt outstanding recovery.
But if we wait for one particular recovery without limit on duration, we may incur penalty
due to various failure scenarios such as stale primary Data Node, etc.
> This JIRA continues the work for 0.95 / trunk.
