Subject Re: How to add/remove slave nodes on run time
Date Fri, 11 Jul 2008 22:56:54 GMT
To add new datanodes, use the same hadoop version already running on your cluster, the right
config and start datanode on any node. The datanode would be configured to talk to the namenode
by reading the configs and it would join the cluster. To remove datanode(s) you could decommission
the datanode and once decommissioned just kill DataNode process. This is described in there
http://wiki.apache.org/hadoop/FAQ#17

Thanks,
Lohit

Subject: How to add/remove slave nodes on run time

Hi,

I searched a bit but could not find the answer. What is the right way
to add (and remove) new slave nodes on run time? Thank you.
