------------------------------------
Shortly after the StackOverflowError it also started spitting this exception:
2010-11-19 12:09:50,366 WARN org.apache.hadoop.hbase.master.AssignmentManager:

> Stack overflow in AssignmentManager

> Key: HBASE-3263
> URL: https://issues.apache.org/jira/browse/HBASE-3263
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 0.90.0
> Reporter: Todd Lipcon
> Priority: Blocker
> Attachments: stackoverflow-log.txt
>
>
> My test cluster experienced a switch outage earlier this week which threw the
> master into a really bad state. In the catch clause of
> AssignmentManager.assign, we recurse, and if all of the region servers are
> inaccessible, we do so until we get a stack overflow.
