Hi, I have hbase setup in pseudo distributed atop HDFS ( again pseudo distributed mode ) in production. This Hbase version is 0.94.7 and Hadoop version is 1.1.2.
I was planning to have a fully distributed 2 node cluster on 2 new machines with latest stable Hbase and Hadoop versions and then copy data from existing cluster to this new cluster using copyTable.
But now i have to add a new machine in existing psuedo distributed mode cluster to make it in distributed mode.
My question is how this can be achieved cleanly.
My another concern is "dfs.replication" property which i set to one in both Hadoop and Hbase configuration.So when i upgrade existing pseudo distributed mode to fully distributed , how will data be replicated to newly added machine ?
Also will regions automatically move to new machine or i will have to run some shell command to manually move it (balance command ) ?
Thanks and Regards, Vimal Jain
Re: Upgrading from pseudo distributed mode to fully distributed mode
Afaik. You can follow the same steps to add or commission a node. Make sure u set the property in hbase-site.xml to let hbase know that its now going to be in a distributed mode after u add the machine. A restart would be required in this case.
The regions will auto balance.
