----------------------------------------

             Summary: Dictionary file is locked for Updation
                 Key: CARBONDATA-585
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-585
             Project: CarbonData
          Issue Type: Bug
            Reporter: Pallavi Singh


On the execution of the following query :
LOAD DATA inpath 'hdfs://localhost:54310/csv/test.csv' INTO table employee options('DELIMITER'=',',
'FILEHEADER'='id, firstname');

The load gets successful at times but we also end up often with the following error :
Dictionary file is locked for Updation.

Following below are the logs :
