GitHub user nareshpr opened a pull request:

    [CARBONDATA-1063] NullPointerException is thrown if multi user beeline is used concurrently

    User1 in beeline terminal1 performs below operation
    1) Create table t1
    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.
