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

             Summary: Fix showing negative pruning result for explain command
                 Key: CARBONDATA-2902
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2902
             Project: CarbonData
          Issue Type: Bug
            Reporter: jiangmanhua
            Assignee: jiangmanhua


 when CACHE_LEVEL is BLOCK or carbon data file is LegacyStore,   pruned result of default datamap are assigned with blocklet_id = -1, which means all blocklets in block need to be scanned. But explain command takes pruned result size as blocklets hit.

If only 2 of 3 blocklet in one block is hit, negative pruning result  `1 (block) - 2(blocklet）= -1 ` occur
