[jira] [Commented] (HIVE-13335) get rid of TxnHandler.TIMED_OUT_TXN_ABORT_BATCH_SIZE

    [ https://issues.apache.org/jira/browse/HIVE-13335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15889138#comment-15889138 ] 

Eugene Koifman commented on HIVE-13335:
---------------------------------------

on 2nd thought it's better to keep this to safeguard against extremely large number of Hive transactions to abort (and keep DB undo log reasonable) but increase the batch size so that we run fewer queries
