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