Venkata Ramana G updated CARBONDATA-1063:
-----------------------------------------
Description:
User1 in beeline terminal1 performs below operation
1) Create table t1
2) show segments for t1
User2(Does not have privilege to read t1) in beeline terminal2 performs below
operation
1) show segments for t1 -- Throws permission denied and removes the CarbonTable
metadata from CarbonMetadata
User1 in beeline terminal1 performs below operation
1) Show segments for t1 - NullPointerException is thrown as the CarbonTable is
not fetched from CarbonMetastore, instead fetched from SingleTon Instance
CarbonMetadata.
This is corrected by fetching the carbonTable from CarbonMetastore of
corresponding Session.
