> to TRACE

> Key: HBASE-6105
> URL: https://issues.apache.org/jira/browse/HBASE-6105
> Project: HBase
> Issue Type: Task
> Affects Versions: 0.95.2
> Reporter: Andrew Purtell
>
> Speaking with Arjen from Facebook ops at HBaseCon, I asked if given one
> single request for improving HBase operability, what would that be. The
> answer was to be less verbose at INFO log level. For example, with many
> regions opening, anomalous events can be difficult to pick out among the 5-6
> INFO level messages per region deployment. Where multiple INFO level messages
> are printed in close succession, we should consider coalescing them. For all
> INFO level messages, we should be aggressive about demoting them to DEBUG
> level. And, since we are now increasing the verbosity at DEBUG level, the
> same considerations should be applied there, with coalescing and demotion of
> really detailed/low level logging to TRACE.
> Consider making this a blocker.
