             Summary: LLAP: force evict blocks by size to handle memory fragmentation
                 Key: HIVE-14172
                 URL: https://issues.apache.org/jira/browse/HIVE-14172
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


In the long run, we should replace buddy allocator with a better scheme. For now do a workaround for fragmentation that cannot be easily resolved. It's still not perfect but works for practical  ORC cases, where we have the default size and smaller blocks, rather than large allocations having trouble.
