Hi
I have a strange error in log of HBase (0.90.2)

then few line later i can see
2011-11-28 15:12:53,139 INFO

So can i deduce that even if the first operation failed everything is ok,
or is something is lost?
Second and Certainly i need to post this question to hdfs guys, (since this
is a dfs output) - from the first line i see that the same node that is the
source of the request will add itself as a dead node isn't it strange?
Regards,
Mikael.S
