Rohini Palaniswamy created HIVE-2988: ----------------------------------------
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. -- This message is automatically generated by JIRA.
