Subject Dynamic Cluster Node addition
Date Fri, 01 Jul 2011 03:56:16 GMT
Hey there,

i am trying to add a new datanode/tasktracker to a currently running
cluster.

Is this feasible? And if yes, how do i change the masters, slaves and
dfs.replication(in hdfs-site.xml) configuration?

can i add the new slave to the slaves configuration file while the cluster
is running?

i found this ./bin/hadoop dfs -setrep -w 4 /path/to/file command to change
the dfs.replication on the fly.

Is there a better way to do it?



Thank you for your kind attention.


Kind Regards,
Paul
