Did it? It shouldn't. If it does, then its a bug we need to figure.
Whats its log say? Otherwise you could do the rebalance manually but
your results will be spotter (Up replication, let it run a while, then
selectively shutdown nodes checking filesystem as you go to make sure at
least one replica is still being served and then restore original
replication level, etc.).

Hi Michael.After reformatting HDFS, Hbase started to work as a Swiss
Clock.
Worked with 8 clients about 30 hours intensive load.
Thanks for reporting back to the list.
Just small question, after about 28 hours (when i came back to work) i
found
that one of 7 datanodes in Hadoop is about 98% usage and all other about
30%, is it normal ?
I haven't kept a close eye on HDFS usage during hbase upload. I do know
that out-of-balance would seem to be a common condition and that its been
reported on the list that hbase runs faster on a balanced HDFS. You might
try out the hadoop balancer. There's a little note on it here in the hbase
FAQ: http://wiki.apache.org/hadoop/Hbase/FAQ#7.
