             Summary: LLAP: consider adding a background thread to defragment 
cache
                 Key: HIVE-16685
                 URL: https://issues.apache.org/jira/browse/HIVE-16685
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


See HIVE-16233; this will be split from that patch, since for now with cache 
always being full it may not be so useful with heavy workloads
