Description
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:
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: java.lang.NumberFormatException: For input string: "4294967296"

Instead, this value should be set in MBs for success.
Thanks,
Laurel
