> As far as I can tell, TableInputFormat creates an instance of HTable which is used by
TableRecordReaderImpl. However TableRecordReaderImpl.close() only closes the scanner, not
the table. In turn the HTable's HConnection's reference count is never decreased which leads
to leaking HConnections.
> TableOutputFormat might have a similar bug.
