https://github.com/apache/carbondata/pull/2368 [CARBONDATA-2603] Fix: error handling during reader build failure
problem : When the CarbonReaderBuilder.build() is failed due to some problems like invalid projection that leads to query model creation failure. Blocklet datamap is not cleared for that table.So, the next reader instance uses old blocklet datamap . That creates error.
Solution: Clear the blocklet datamap if the reader build is failed.
