> 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
