> Project: HBase
> Issue Type: Bug
> Components: master, regionserver
> Affects Versions: 0.89.20100924, 0.90.0
> Reporter: Jonathan Gray
> Assignee: ryan rawson
> Priority: Critical
> Fix For: 0.90.0

>
> During a rolling restart, we ran into a case where a master was shutdown and then brought back up before the znode expired.
> On the RS side, while the master was down, it was getting ConnectionRefused exceptions trying to heartbeat to what it thinks is the active master.
> Once the master process comes back up, the next heartbeat done by all the RSs just blocks indefinitely.
> This is somewhat related to HBASE-3141
