> Hive should handle AlreadyExists on retries when creating tables/partitions
> ---------------------------------------------------------------------------
>
> Key: HIVE-4897
> URL: https://issues.apache.org/jira/browse/HIVE-4897
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Assignee: Aihua Xu

>
> Creating new tables/partitions may fail with an AlreadyExistsException if
> there is an error part way through the creation and the HMS tries again
> without properly cleaning up or checking if this is a retry.
> While partitioning a new table via a script on distributed hive (MetaStore on
> the same machine) there was a long timeout and then:
> {code}
> FAILED: Execution Error, return code 1 from
> org.apache.hadoop.hive.ql.exec.DDLTask.
> AlreadyExistsException(message:Partition already exists:Partition( ...
> {code}
> I am assuming this is due to retry. Perhaps already-exists on retry could be
> handled better.
> A similar error occurred while creating a table through Impala, which issued
> a single createTable call that failed with an AlreadyExistsException. See the
> logs related to table tmp_proc_8_d2b7b0f133be455ca95615818b8a5879_7 in the
> attached hive-snippet.log
