Travis Crawford commented on HCATALOG-587:
------------------------------------------
Sounds good! +1 to
[HCATALOG-587.2.patch|https://issues.apache.org/jira/secure/attachment/12565179/HCATALOG-587.2.patch]
if tests pass.
I'll file a followup about clarifying how to use AppConfig.

> The webhcat map only task does not need lot of memory. But when a java
> application is started with -server option, it allocates the memory specified
> as max heap size (-Xmx in oracle jre) upfront.
> When combined with the memory used by pig or hive client, this can sometimes
> exceed the maximum memory limit for a map task (if configured).
> Being able to specify the java options for the map task will be useful to
> avoid this issue.
