Hi, I am new in Hadoop. I created a four nodes cluster 3 slaves, and 1 master (this is onyl the test system). It works fine, i used this howto: http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-multi-node-cluster/. My question is, what is the best solution to make the master(namenode) fail over, i read a lot, but i dont now what is the best. I found this howto: http://www.cloudera.com/blog/2009/07/hadoop-ha-configuration/ , but if it is possible, i do not want to use DRBD. I hope somebody can help me. Sorry my english.... :)
Thanks. Tibi
