> Currently recoverLease API will return true if file is already closed.
> Otherwise it will trigger internalLease recovery and return false. It may
> take some time to really complete this recovery and file to be closed
> completely. So, there is noway for the users to wait correctly until file is
> closed completely.
> It would good if we have one API which says whether that file is closed or
> not. So, that users can relay on that proceed further if and only if file is
> closed completely.
> See the discussion in HBASE-7878
