                 URL: https://issues.apache.org/jira/browse/CARBONDATA-241
             Project: CarbonData
          Issue Type: Bug

            Assignee: kumar vishal

**Problem:** During long run query execution is taking more time and it is 
throwing out of memory issue.
**Reason**: In compaction we are compacting segments and each segment metadata 
is loaded in memory. So after compaction compacted segments are invalid but its 
meta data is not removed from memory because of this duplicate metadata is pile 
up and it is taking more memory and after few days query exeution is throwing 
**Solution**: Need to remove invalid blocks from memory
