[jira] [Created] (IMPALA-8562) Data cache should skip file with mtime == -1

Michael Ho created IMPALA-8562:
----------------------------------

             Summary: Data cache should skip file with mtime == -1
                 Key: IMPALA-8562
                 URL: https://issues.apache.org/jira/browse/IMPALA-8562
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 3.3.0
            Reporter: Michael Ho
            Assignee: Michael Ho


As show in IMPALA-8561, using mtime == -1 as part of cache key may lead to reading stale data. Data cache should probably just skip caching those entries.
