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
