Michael Bieniosek commented on HBASE-879:
-----------------------------------------
The regionserver throws an exception like "Can't get block location" or "all
datanodes are bad"; this exception is then thrown back to the client.
> When dfs restarts or moves blocks around, hbase regionservers don't notice
> --------------------------------------------------------------------------

> Key: HBASE-879
> URL: https://issues.apache.org/jira/browse/HBASE-879
> Project: Hadoop HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.2.0
> Reporter: Michael Bieniosek
>
> Since the hbase regionservers use a DFSClient to keep handles open to the
> dfs, if the dfs blocks move around (typically because of a dfs restart, but
> can also happen if datanodes die or blocks get shuffled around), the
> regionserver will be unable to service the region. It would be nice if the
> DFSClient that the regionservers use could notice this case and refresh the
> block list.
