> URL: https://issues.apache.org/jira/browse/HIVE-28788
> Project: Hive
> Issue Type: Bug
> Reporter: Zhihua Deng
> Assignee: Zhihua Deng
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.1.0
>
>
> If there is an exception on committing the transaction,
> [https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L658,]
> the ObjectStore will skip the transaction rollback, as the
> openTrasactionCalls is 0, the current transaction might be alive until the
> RetryingHMSHandler retries the operation(after 2s) or the client closes the
> connection, leading to the connection starvation during that time.
