Ganesha Shreedhara updated HIVE-18859:
--------------------------------------
Status: Open (was: Patch Available)
> Incorrect handling of thrift metastore exceptions
> -------------------------------------------------
>
> Key: HIVE-18859
> URL: https://issues.apache.org/jira/browse/HIVE-18859
> Project: Hive
> Issue Type: Bug
> Affects Versions: 2.1.1, 1.2.0
> Reporter: Ganesha Shreedhara
> Assignee: Ganesha Shreedhara
> Priority: Major
>
> Currently any run time exception thrown in thrift metastore during the
> following operations is not getting sent to hive execution engine.
> * grant/revoke role
> * grant/revoke privileges
> * create role
> This is because ThriftHiveMetastore just handles MetaException and throws
> TException during the processing of these requests. So, the command just
> fails at thrift metastore end when there is run time exception (Exception can
> be seen in metastore log) but the hive execution engine will keep on waiting
> for the response from thrift metatstore.
>
> Steps to reproduce this problem :
> Launch thrift metastore
> Launch hive cli by passing --hiveconf
> hive.metastore.uris=thrift://127.0.0.1:10000 (pass the thrift metatstore host
> and port)
> Execute the following commands:
> # set role admin
> # create role test; (succeeds)
> # create role test; ( hive version 2.1.1 : command is stuck, waiting for the
> response from thrift metastore; hive version 1.2.1: command fails with
> exception as null)
>
> I have uploaded the patch which has the fix in which I am handling the
> checked exceptions in MetaException and throwing unchecked exceptions using
> TException which fixes the problem. Please review and suggest if there is a
> better way of handling this issue.
