Dear all
I'm sorry to disturb you.
Our cluster has 200 nodes now. In order to improve its ability, we hope
to add 60 nodes into the current cluster. However, we all don't know what
will happen if we add so many nodes at the same time. Could you give me some
tips and notes? During the process, which part shall we pay much attention
on?
Thank you!
P.S. Our environment is hadoop-0.19.1, jdk1.6.0_06, linux redhat
enterprise 4.0
