> Null pointer exception on running compaction against a MM table.
> ----------------------------------------------------------------
>
> Key: HIVE-21280
> URL: https://issues.apache.org/jira/browse/HIVE-21280
> Project: Hive
> Issue Type: Bug
> Affects Versions: 3.0.0, 3.1.1
> Reporter: Aditya Shah
> Priority: Major
>
> On running compaction on MM table, got a null pointer exception while getting
> HDFS session path. The error seemed to me that the session state was not
> started for these queries. Even after making it start it further fails in
> running a Teztask for insert overwrite on temp table with the contents of the
> original table. The cause for this is Tezsession state is not able to
> initialize due to Illegal Argument exception being thrown at the time of
> setting up caller context in Tez task due to caller id which uses queryid
> being an empty string.
> I do think session state needs to be started and each of the queries running
> for compaction (I'm also doubtful for stats updater thread's queries) should
> have a query id. Some details are as follows:
> Steps to reproduce:
> 1) Using beeline with HS2 and HMS
> 2) create an MM table
> 3) Insert a few values in the table
> 4) alter table mm_table compact 'major';
> Stack trace on HMS:
> {code:java}
> compactor.Worker: Caught exception while trying to compact
> id:8,dbname:default,tableName:acid_mm_orc,partName:null,state:^@,type:MAJOR,properties:null,runAs:null,tooManyAborts:false,highestWriteId:0.
