> Our new users get confused when they see their region servers disappearing.
> If they are proactive enough, they even show us with some messages like:
> {code}
> 2010-03-28 20:24:27,439 WARN org.apache.hadoop.hbase.util.Sleeper: We slept
> 79410ms, ten times longer than scheduled: 5000
> 2010-03-28 20:24:27,439 WARN org.apache.hadoop.hbase.util.Sleeper: We slept
> 78781ms, ten times longer than scheduled: 3000
> {code}
> For us it's very obvious what just happened, for our users not at all. I
> think we could easily just create a very comprehensive entry about this issue
> in the troubleshooting page and put a link directly into the error message.
