Subject [jira] Commented: (HBASE-2223) Handle 10min+ network partitions between clusters
Date Fri, 12 Feb 2010 20:54:28 GMT

Jean-Daniel Cryans commented on HBASE-2223:
-------------------------------------------

That's my thinking too, so probably that the first version of this tool will just help the
hbase administrator make the right choices.

> We need a nice way of handling long network partitions without impacting a master cluster
(which pushes the data). Currently it will just retry over and over again.
> I think we could:
>  - Stop replication to a slave cluster if it didn't respond for more than 10 minutes
>  - Keep track of the duration of the partition
>  - When the slave cluster comes back, initiate a MR job like HBASE-2221 
> Maybe we want less than 10 minutes, maybe we want this to be all automatic or just the
first 2 parts. Discuss.
