Bryan Duxbury commented on HBASE-12:
------------------------------------
What should we do when this exception shows up? Immediately cancel the existing
lease? Let the lease time out and have the RegionServer keep retrying?
I think we should add to the error message and describe possible causes and
resolutions. Something like "Check your DNS configuration so that all region
servers are reporting their true IPs and not 127.0.0.1. Otherwise, this problem
will resolve itself in ${lease-timeout} seconds."
> when hbase regionserver restarts, it says "impossible state for createLease()"
