[jira] [Created] (KUDU-1939) Demote or remove WARNING about large arenas

Todd Lipcon created KUDU-1939:
---------------------------------

             Summary: Demote or remove WARNING about large arenas
                 Key: KUDU-1939
                 URL: https://issues.apache.org/jira/browse/KUDU-1939
             Project: Kudu
          Issue Type: Improvement
          Components: util
    Affects Versions: 1.3.0
            Reporter: Todd Lipcon
            Priority: Minor


Currently whenever an arena fills up to more than 256MB, a warning is issued with a stack trace. This is very common in the case of MRS arenas, which will often be larger than 256MB.

The original intent of the warning was to catch cases where we were forgetting to Reset() an arena during a scan/compaction/etc. Given that, maybe we should be setting the "warning threshold" on a per-arena basis, or at least give the ability to suppress the warning for MRS/DMS where large arenas are the norm.
