Kunal Kapoor created CARBONDATA-2967:
----------------------------------------
Summary: 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: Improvement
Reporter: Kunal Kapoor
Assignee: Kunal Kapoor
*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.
