Hi,

after our issues ("Replay of HLog required", in a precious thread) with HBase, it seems that
HBase has corrupted regions.
We have, on the three region servers, errors stating that HBase cannot open certain regions
because some map files on hdfs are missing (see the log attached).

Do you have any ideas how to fix this ?

Thanks.

I'd thought we'd added handling of this kind of event post HDFS crashings but looking in code,
it seems that TRUNK may not have been fixed up properly.
