ATTACHMENT ID: 12693758 - PreCommit-HIVE-TRUNK-Build
> Export of a large table causes OOM in Metastore and Client
> ----------------------------------------------------------
>
> Key: HIVE-9359
> URL: https://issues.apache.org/jira/browse/HIVE-9359
> Project: Hive
> Issue Type: Bug
> Components: Import/Export, Metastore
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
> Attachments: HIVE-9359.2.patch, HIVE-9359.patch
>
>
> Running hive export on a table with a large number of partitions winds up
> making the metastore and client run out of memory. The number of places we
> wind up having a copy of the entire partitions object wind up being as
> follows:
> Metastore
> * (temporarily) Metastore MPartition objects
> * List<Partition> that gets persisted before sending to thrift
> * thrift copy of all of those partitions
> Client side
> * thrift copy of partitions
> * deepcopy of above to create List<Partition> objects
> * JSONObject that contains all of those above partition objects
> * List<ReadEntity> which each encapsulates the aforesaid partition objects.
> This memory usage needs to be drastically reduced.
