100000
- Added In: Hive 2.0.0 with HIVE-9453
Development of an HBase metastore for Hive started in release 2.0.0 (HIVE-9452) but the work has been stopped and the code was removed from Hive in release 3.0.0 (HIVE-17234).
Many more configuration properties were created for the HBase metastore in releases 2.x.x – they are not documented here. For a full list, see the doc note on HIVE-17234.
hive.metastore.hbase.cache.size
(This configuration property should never have been documented here, because it was removed before the initial release by HIVE-9693.)Maximum number of objects we will place in the HBase metastore cache. The objects will be divided up by types that we need to cache.
hive.metastore.hbase.cache.ttl
- Default Value: 600s
- Added In: Hive 2.0.0 with HIVE-9453
- Removed In: Hive 3.0.0 with HIVE-17234
