Ted Yu commented on HBASE-10330:
--------------------------------
TableOutputFormat doesn't have this problem:
{code}
public void close(TaskAttemptContext context)
throws IOException {
table.close();
}
{code}
> TableInputFormat/TableRecordReaderImpl leaks HTable

> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.96.0
> Reporter: G G
> Assignee: Ted Yu

> Attachments: 10330-v1.txt

>
> 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.
