Zsolt Fekete reassigned HIVE-16719:
-----------------------------------
> HiveMetaTool fails when the data does not fit in memory
> -------------------------------------------------------
>
> Key: HIVE-16719
> URL: https://issues.apache.org/jira/browse/HIVE-16719
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Reporter: Zsolt Fekete
> Assignee: Zsolt Fekete
>
> Currently HiveMetaTool reads full tables (as DataNucleus entities) into
> memory by calling PersistenceManager's retrieveAll().
> See these methods of ObjectStore: updateMDatabaseURI, updateTblPropURI,
> updateMStorageDescriptorTblPropURI, updateMStorageDescriptorTblURI,
> updateSerdeURI.
> This might cause failure when the affected tables (SDS, DBS, TABLE_PARAMS,
> SD_PARAMS, SERDES, SERDE_PARAMS) are too big.
