Jean-Daniel Cryans resolved HBASE-2410.
---------------------------------------
Resolution: Fixed
Hadoop Flags: [Reviewed]
I committed to branch and trunk a fix that checks for a delta of 10 seconds
between the time slept and the period.
> spurious warnings from util.Sleeper

> Project: Hadoop HBase
> Issue Type: Bug
> Reporter: Andrew Purtell

> Priority: Blocker
> Fix For: 0.20.4, 0.21.0
>
> Attachments: HBASE-2410.patch

> Many of this in the logs
> {noformat}
> WARN util.Sleeper: We slept 59993ms, this is likely due to a long garbage
> collecting pause and it's usually bad, see
> http://wiki.apache.org/hadoop/Hbase/Troubleshooting#A9
> {noformat}
> except this is the MetaScanner and the sleeper has a period of 60000ms. I
> have one of 30000ms in Stargate which is doing the same thing now.
> I see the intent but these spurious warnings defeat the intent here. Marked
> as blocker as this will cause no end of users writing in on the list. Should
> be a test of the actual sleep time against the configured interval, not a
> constant.
