Lars Hofhansl resolved HBASE-4202.
----------------------------------
Resolution: Won't Fix
Alright. Can always reopen.
(We're doing some jira house cleaning at Salesforce)
> Check filesystem permissions on startup
> ---------------------------------------
>
> Key: HBASE-4202
> URL: https://issues.apache.org/jira/browse/HBASE-4202
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.20.4
> Environment: debian squeeze
> Reporter: Matthias Hofschen
> Assignee: ramkrishna.s.vasudevan
> Priority: Trivial
> Labels: noob
>
> We added a new node to a 44 node cluster starting the datanode, mapred and
> regionserver processes on it. The Unix filesystem was configured incorrectly,
> i.e. /tmp was not writable to processes. All three processes had issues with
> this. Datanode and mapred shutdown on exception.
> Regionserver did not stop, in fact reported to master that its up without
> regions. So master assigned regions to it. Regionserver would not accept
> them, resulting in a constant assign, reject, reassign cycle, that put many
> regions into a state of not being available. There are no logs about this,
> but we could observer the regioncount fluctuate by hundredths of regions and
> the application throwing many NotServingRegion exceptions.
> In fact to the master process the regionserver looked fine, so it was trying
> to send regions its way. Regionserver rejected them. So the master/balancer
> was going into a assign/reassign cycle destabilizing the cluster. Many puts
> and gets simply failed with NotServingRegionExceptions and took a long time
> to complete.
