Laurel Hale reassigned HIVE-16735:
----------------------------------
> Please add that hive.mapred.local.mem must be set in MBs in the documentation
> -----------------------------------------------------------------------------

> Key: HIVE-16735
> URL: https://issues.apache.org/jira/browse/HIVE-16735
> Project: Hive
> Issue Type: Task
> Components: Documentation
> Reporter: Laurel Hale
> Assignee: Lefty Leverenz
> Priority: Minor

> Hi Lefty,
> One of my developers noticed this and we do not document the local mode.
> Thought I'd let you know.
> Here's a good place where you could put this:
> https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution
> There's already a small subsection where hive.mapred.local.mem is documented,
> but there isn't any information about how to set the value. My developer
> discovered that when you set it in bytes, it throws the following error:
> 2017-03-12 09:24:31,835 ERROR [HiveServer2-Background-Pool: Thread-22163()]:
> mr.MapredLocalTask (MapredLocalTask.java:executeInChildVM(341)) - Exception:

> org.apache.hadoop.hive.ql.exec.mr.MapredLocalTask.executeInChildVM(MapredLocalTask.java:228)
> Instead, this value should be set in MBs for success.
> Thanks,
> Laurel
