What will we encounter if we add a lot of nodes into the current cluster?
-------------------------------------------------------------------------

                 Key: HDFS-541
                 URL: https://issues.apache.org/jira/browse/HDFS-541
             Project: Hadoop HDFS
          Issue Type: Test
         Environment: hadoop-0.19.1
jdk1.6.0_06
linux redhat enterprise 4
            Reporter: nju.inifok


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!
