Edward Capriolo commented on HIVE-2988:
---------------------------------------
I think the patch is great, but the JDK heap default is 512MB in recent JDKs. I
know 4K of ram job a man to the moon, but why are you running such a low
default?
> Use of XMLEncoder to serialize MapredWork causes OOM in hive cli

> Reporter: Rohini Palaniswamy
> Labels: Performance

> When running queries on tables with 6000 partitions, hive cli if configured
> with 128M runs into OOM. Heapdump showed 37MB occupied by one XMLEncoder
> object while the MapredWork was 500K which is highly inefficient. We should
> switch to using something more efficient like XStream.
