Adding new data nodes to Hadoop without rebooting

Usually, I have been wonder how to new data nodes (or recovered nodes) to Hadoop without rebooting. Recently, I found the solution from hadoop core-user mailing list.

The way is very simple as follows:

1. configure conf/slaves and *.xml files on master machine
2. configure conf/master and *.xml files on slave machine
3. run ${HADOOP}/bin/hadoop datanode

If you have to add more than one data node to Hadoop, run the following command (instead of the third command above) on master machine.

${HADOOP}/bin/start-all.sh

Additionally, the way to add a region server to Hbase master without restarting all is similar to that of Hadoop.

1. configure conf/regionservers and *.xml files on master machine
2. configure conf/*.xml files on slave machine
3. run ${HBASE}/bin/hbase regionserver start
