Kunal Kapoor updated CARBONDATA-2967:
-------------------------------------
Issue Type: Bug (was: Improvement)
> Select is failing on pre-aggregate datamap when thrift server is restarted.
> ---------------------------------------------------------------------------
>
> Key: CARBONDATA-2967
> URL: https://issues.apache.org/jira/browse/CARBONDATA-2967
> Project: CarbonData
> Issue Type: Bug
> Reporter: Kunal Kapoor
> Assignee: Kunal Kapoor
> Priority: Major
>
> *Problem:*
> NullPointerException is thrown when select query is fired on a datamap. This
> is because to access dictionary files of the parent table the child table
> tries to get tablePath from CarbonTable object of the parent. Because the
> metadata is not populated therefore NullpointerException is thrown.
