spurious warnings from util.Sleeper
-----------------------------------
Key: HBASE-2410
URL: https://issues.apache.org/jira/browse/HBASE-2410
Project: Hadoop HBase
Issue Type: Bug
Reporter: Andrew Purtell
Priority: Blocker
Fix For: 0.20.4, 0.21.0
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.
