[jira] [Commented] (HIVE-12418) HiveHBaseTableInputFormat.getRecordReader() causes Zookeeper connection leak.

["Naveen Gangam (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-12418?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15008830#comment-15008830 ] 

Naveen Gangam commented on HIVE-12418:
--------------------------------------

The proposed fix closes the HTable resources when RecordReader.close() is called. Also overrides the Object.finalize() that closes these resources too in cases when RecordReader.close() is never called.
