Hi,
I'm trying to decommission a RS, i.e. migrate all regions to different
nodes in order to shutdown that specific node. First I've moved all
regions to different nodes and made sure that there are no regions
anymore on this node:
...
ip-11-11-111-111.ec2.internal:60020 1362060123906
requestsPerSecond=0, numberOfOnlineRegions=0, usedHeapMB=118,
maxHeapMB=9974
...
After moving the regions I've stopped the HBase and Hadoop services on
the decommissioned. I though that's it but now when accessing the moved
regions on the new nodes I get error messages in the logs that blocks
are not being found...On the decommissioned node I can still see many
blk_* files in the HDFS. Is there anything else that needs to be done to
fully transfer all region data to the new nodes? It looks like the
regions are transferred but the related data is still on the old
node...Maybe the replication factor of only 1 (I know....) is the problem?!?
I'm using HBase 0.92.0 btw.
Thanks
Yves
