thank you Azuryy, I have encountered an problem of hbase, but I don't know
whether it was caused by ip change or not. because we started the system
for about 2 hours, then second name server exited .... all cluster can't
bring up...,hbase data is corrupt .... it's a long miserable story...

hi,
I solved this problem last week.
stop-hbase -> change zkdata property directory(same as delete zk data) ->
change ip, hostname -> start-hbase
all resions will be reassigned. if you have lots of regions, it's very very
slow. I think there is no answer for this slow process until 0.96.

You need not to do this. All region will be re-assigned and all meta information will be updated itself.

Which version are you using? It's not recommended to do so, I think, but I'm not sure.

thanks，jieshan!
are you Chinese? I'm worry about the meta data of HBase, I have to modify
it manually? to Zookeeper, if i just remove the zk data, it will be ok?

thanks，jieshan!
are you Chinese? I'm worry about the meta data of HBase, I have to modify
it manually? to Zookeeper, if i just remove the zk data, it will be ok?

I think one problem is there is Zookeeper: ZK stores the ip and hostname mappings locally(We encountered one issue long time before. The cluster was recovered after we deleted the directory of dataDir/version.).
I think there will be no impact from Hbase side.
