Re: How to upgrade HBase from 0.90.5 to 0.94

2013-01-17 Thread Mickey 
Thanks, Ted.
If I have another cluster already installed with hbase 0.94.4, can I
migrate the data from the original hbase 0.90 cluster to the new cluster?
 Is it possible to do something like bulk load?

Best regards,
Mickey

With the version gap I don't think bulk load can be used directly. 

Do the two clusters have same set of tables ?
Is the 0.90 cluster serving write load actively ?

Thanks

You can upgrade to 0.92.2 first, followed by upgrade to 0.94.4

Please consider upgrading Hadoop to 1.0.4 as well

Thanks
