Jean-Daniel Cryans commented on KUDU-1939:
------------------------------------------
I 100% agree. We should only warn about actual problems, else we end up with
warn fatigue. That log really looks scary too.
> 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
> Labels: newbie
>
> 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.
