[jira] [Commented] (HIVE-12009) Add IMetastoreClient.heartbeat(long[] lockIds)

    [ https://issues.apache.org/jira/browse/HIVE-12009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14940386#comment-14940386 ] 

Eugene Koifman commented on HIVE-12009:
---------------------------------------

actually this should not be necessary.  the only time you can have > 1 'ext' lock is when there is a transaction open, thus it's better to heartbeat the txn

> Add IMetastoreClient.heartbeat(long[] lockIds)

> Current API only allows heart beating 1 lock ID (external ID) at a time.
> For multi statement txns we can have multiple locks per txn and should be able to do it in 1 cal.
> Used from DbTxnManager.heartbeat()
