----------------------------------------
Summary: Use of XMLEncoder to serialize MapredWork causes OOM in
hive cli
Key: HIVE-2988
URL: https://issues.apache.org/jira/browse/HIVE-2988
Project: Hive
Issue Type: Improvement
Components: CLI
Reporter: Rohini Palaniswamy
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.
