- hive.support.concurrency
- hive.enforce.bucketing (Hive 0.x and 1.x only)
- hive.exec.dynamic.partition.mode
Transactions
hive.txn.manager
- Default Value:
org.apache.hadoop.hive.ql.lockmgr.DummyTxnManager - Hive Transactions Value:
org.apache.hadoop.hive.ql.lockmgr.DbTxnManager - Added In: Hive 0.13.0 with HIVE-5843

Compactor
hive.compactor.initiator.on
...
Number of aborted transactions involving a given table or partition that will trigger a major compaction.
Compaction History
hive.compactor.history.retention.succeeded
- Default Value:
3 - Added In: Hive 1.3.0 and 2.0.0 with HIVE-12353
Number of successful compaction entries to retain in history (per partition).
hive.compactor.history.retention.failed
- Default Value:
3 - Added In: Hive 1.3.0 and 2.0.0 with HIVE-12353
Number of failed compaction entries to retain in history (per partition).
hive.compactor.history.retention.attempted
- Default Value:
2 - Added In: Hive 1.3.0 and 2.0.0 with HIVE-12353
Number of attempted compaction entries to retain in history (per partition).
hive.compactor.initiator.failed.compacts.threshold
- Default Value:
2 - Added In: Hive 1.3.0 and 2.0.0 with HIVE-12353
Number of of consecutive failed compactions for a given partition after which the Initiator will stop attempting to schedule compactions automatically. It is still possible to use ALTER TABLE to initiate compaction. Once a manually initiated compaction succeeds auto initiated compactions will resume. Note that this must be less than hive.compactor.history.retention.failed.
hive.compactor.history.reaper.interval
- Default Value:
2m - Added In: Hive 1.3.0 and 2.0.0 with HIVE-12353
Controls how often the process to purge historical record of compactions runs.
