Subject [jira] [Commented] (HIVE-20464) LLAP daemon start fail
Date Mon, 27 Aug 2018 19:29:01 GMT

    [ https://issues.apache.org/jira/browse/HIVE-20464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16594137#comment-16594137

Sergey Shelukhin commented on HIVE-20464:
-----------------------------------------

The error means the memory config is incorrect... executor memory being 0 refers to hive.llap.daemon.memory.per.instance.mb
that is 4Gb by default. Please refer to this doc for an example https://community.hortonworks.com/articles/149486/llap-sizing-and-setup.html
