-----------------------------------
Summary: 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.
