ATTACHMENT ID: 12821507 - PreCommit-HIVE-MASTER-Build
> Handle concurrent insert with dynamic partition
> -----------------------------------------------
>
> Key: HIVE-14400
> URL: https://issues.apache.org/jira/browse/HIVE-14400
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 2.2.0
> Reporter: Wei Zheng
> Assignee: Wei Zheng
> Attachments: HIVE-14400.1.patch, HIVE-14400.2.patch
>
>
> With multiple users concurrently issuing insert statements on the same
> partition has a side effect that some queries may not see a partition at the
> time when they're issued, but will realize the partition is actually there
> when it is trying to add such partition to the metastore and thus get
> AlreadyExistsException, because some earlier query just created it (race
> condition).
> For example, imagine such a table is created:
> {code}
> create table T (name char(50)) partitioned by (ds string);
> {code}
> and the following two queries are launched at the same time, from different
> sessions:
> {code}
> insert into table T partition (ds) values ('Bob', 'today'); -- creates the
> partition 'today'
> insert into table T partition (ds) values ('Joe', 'today'); -- will fail with
> AlreadyExistsException
> {code}
