Subject [jira] Commented: (HIVE-2017) Driver.execute() should maintaining SessionState in case of runtime errors
Date Fri, 04 Mar 2011 11:13:37 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13002546#comment-13002546

Chinna Rao Lalam commented on HIVE-2017:
----------------------------------------

taskCleanup() is calling System.exit(9) it will exit from JVM. Here instead of calling 
System.exit(9) we need to kill the map-reduce & non MR processes

> Driver.execute() should maintaining SessionState in case of runtime errors

> I simply returned in case of runtime errors without maintaining SessionState. It could
cause resource leak mentioned in HIVE-1959.
