stack commented on HBASE-879:
-----------------------------

I'm fine closing this.  The issue Michael talks of in original comment is not 
an issue any more; the DFSClient should pick up blocks in new location getting 
new block locations list from namenode.  Andrew's comment on hbase being able 
to survive a dfs restart under it is still to be fixed (we have other issues to 
cover this though)
                
> When dfs restarts or moves blocks around, hbase regionservers don't notice

> 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.
