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
