Subject [jira] [Commented] (HIVE-8373) OOM for a simple query with spark.master=local [Spark Branch]
Date Fri, 23 Dec 2016 20:37:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15773646#comment-15773646

Andrew Sears commented on HIVE-8373:
------------------------------------

[~lirui] Would be best to control the upper bounds to limit effects of OOM on the entire system.
 There are some memory leaks in Spark that may be caught by setting this to a lower setting.
