User1 in beeline terminal1 performs below operation

2) load data into t1
3) 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.
