stack commented on HADOOP-2662:
-------------------------------
In the master log, what do you see? Its waiting and waiting and then just gives
up after lease timeout because it says the regionservers are taking too long to
report in?
The code doesn't currently accomodate a regionserver that is taking its time
going down because its busy running flushes and outstanding, etc. It probably
should (regionserver reports every so often to the master that its working on
the close).
There should be no data loss in this case (Regionservers are going down
properly -- its just the final report in to the master that its down that is
failing)
> master stopping before regions finish stopping

> Key: HADOOP-2662
> URL: https://issues.apache.org/jira/browse/HADOOP-2662
> Project: Hadoop
> Issue Type: Bug
> Components: contrib/hbase
> Reporter: Billy Pearson
> Priority: Minor
> Fix For: 0.16.1
>
>
> I get this on my region servers logs sometimes when I shutdown the cluster it
> repeats several times sometimes trying to find the master
> I thank we need to look at the master and make sure we do not stop the master
> on exit before all region servers report down.
> I am not sure if there could be data loss or not but we should not leave
> region servers looking for the master unless it has failed on it own.
