[GitHub] [hive] dengzhhu653 commented on pull request #2967: HIVE-25892: Group HMSHandler's thread locals into a single context

URL: https://github.com/apache/hive/pull/2967#issuecomment-1020924354


   > Could we provide a way to clear the context? In Iceberg we create a HMS instance for our tests, and because of the threadlocals here and in the TxnHandler we leak information between the tests.
   
   Add a [CleanupHook](https://github.com/apache/hive/blob/c8c6152b79810276ac070ec057b0643b9ce3b03f/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HMSHandlerContext.java#L170-L172) here to clear the locals by calling HMSHandlerContext#clear(CleanupHook cleanupHook),  not sure it enough for the iceberg case.
