> 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.
