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

             Summary: Array Index of bound exception thrown from dictionary look up while
writing sort index file
                 Key: CARBONDATA-229
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-229
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta


Whenever we load dictionary data into memory, then in case of populating reverse dictionary
object sometimes a chunk which has no value is also getting added to the dictionary chunk
list. This is happening because the logic for dictionary chunk distribution in case of forward
dictionary is not implemented for reverse dictionary and 0 size dictionary chunks are not
getting removed while adding to the list of dictionary chunks.
