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

             Summary: Thread leak in compaction operation if prefetch is enabled and compaction process is killed
                 Key: CARBONDATA-2391
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2391
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta


Problem
Thread leak in compaction operation if prefetch is enabled and compaction process is killed

Analysis
During compaction if prefetch is enabled RawResultIterator launches an executor service for prefetching the data.
If compaction fails or the process is killed it can lead to thread leak due to executor service still in running state.
