----------------------------------------
[~pankaj_kumar] Sure, that's a reasonable idea.

> Key: HBASE-17704
> URL: https://issues.apache.org/jira/browse/HBASE-17704
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 1.1.8
> Reporter: Mathias Herberts
>
> We recently experienced the loss of a whole rack (6 DNs + RS) in a 120 node
> cluster. This lead to the regions which were present on the 6 RS which became
> unavailable to be reassigned to live RSs. When attempting to open some of the
> reassigned regions, some RS encountered missing blocks and issued "No live
> nodes contain current block Block locations" putting the regions in state
> FAILED_OPEN.
> Once the disappeared DNs went back online, the regions were left in
> FAILED_OPEN, needing a restart of all the affected RSs to solve the problem.
