    [CARBONDATA-241]Fixed out of memory issue during query execution

    **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 execution is throwing OOM
    **Solution**: Need to remove invalid blocks from memory
