Subject Re: Region server crashes when using replication
Date Sun, 27 Mar 2011 17:05:30 GMT
So the message "No log to process" means that nothing was assigned to
replicate at all... I wonder if it's HBASE-3664 that did that... but
you should be able to confirm by looking at the region server log when
it starts, it should be adding it's own HLog to the list to replicate.

Regarding the failover, it might be that the log is indeed registered
in zookeeper but somehow isn't in the memory log structure of
ReplicationSourceManager... again the logs should tell.

Feel free to send me directly a big tar.gz with all those logs and I
should be able to figure out.
