---------------------------------------
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.
