             Summary: add cache dump when LLAP cache has issues on branch-2 (and fix retry issues)
                 Key: HIVE-19642
                 URL: https://issues.apache.org/jira/browse/HIVE-19642
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


LLAP cache doesn't have defragmentation on branch-2 so it retries when failing to evict.
There are a couple of issues with retries (e.g. sleep is not applied properly and time can go negative), also it would be helpful to make use of existing cache dump logic used in LLAP IO view to dump log state into the log in such cases.
