Hi,
I recently had an IP reshuffle, thereby changing the IP addresses of
all nodes. I had used aliases everywhere in hadoop and hbase config
directories. So, I think I only need to change the IPs in the /etc/hosts
file, which is what I did. But ever since the IP change, I am getting a lot
of HBaseRPC: Could not connect to 192.168.x.y:60020, where 192.168.x.y are
the new IPs. I am unable to figure out the reason for these errors. Do I
need to update the IPs anywhere else as well? I have also found that the
datanode VERSION files have mention of the old IPs:
#Thu Nov 11 15:50:49 IST 2010
namespaceID=815609148
storageID=DS-1497184272-192.168.0.158-50010-1288777337532
cTime=0
storageType=DATA_NODE
layoutVersion=-18
(192.168.0.158 is the old IP of the datanode which has this VERSION file. I
have found the same old IPs in the other datanodes as well.)
So, do the VERSION files also need to be updated?
thanks,
Hari
