Mithun Radhakrishnan reassigned HIVE-17612:
-------------------------------------------
> Hive does not insert dynamic partition-sets atomically
> ------------------------------------------------------
>
> Key: HIVE-17612
> URL: https://issues.apache.org/jira/browse/HIVE-17612
> Project: Hive
> Issue Type: Improvement
> Components: CLI, Hive
> Affects Versions: 2.2.0, 3.0.0
> Reporter: Mithun Radhakrishnan
> Assignee: Mithun Radhakrishnan
>
> If one inserts partitions to a Hive table using a Hive query (e.g. {{INSERT
> OVERWRITE TABLE my_table PARTITION (foo, bar) SELECT * FROM
> another_table;}}), each dynamic partition is added separately, using
> {{HMSC.append_partition()}}. By contrast, Pig/HCatLoader does the same
> atomically, using {{HMSC.add_partitions()}}.
> Because of this behaviour, Oozie workflows might kick off when the first
> partition is registered, but before the last partition in the set is
> available.
> This was verified in the metastore-logs, with multiple {{ADD_PARTITION}}
> events fired for the same query (i.e. once per added partition), instead of a
> single event for the set.
> It would be ideal for Hive to provide atomic partition-adds.
