Hi, I got couple of doubts while doing this. Please help me to understand that. How to generate or find out the the cluster id for the below step? I saw that for one node we can format without this cluster id and we need to pass same cluster id which got generated for the other name node while formatting or else we could not get the federated cluster. $HADOOP_PREFIX_HOME/bin/hdfs namenode -format -clusterId <cluster_id>In my case i want to have two name nodes and 3 data nodes. Do i need to mention all the data nodes ip address in the slave files in two name nodes?
Thanks,Manickam P Date: Mon, 23 Sep 2013 10:02:42 -0700 Subject: Re: HDFS federation Configuration From: sur...@hortonworks.com To: user@hadoop.apache.org I'm not able to follow the page completely. Can you pls help me to get some clear step by step or little bit more details in the configuration side? Have you setup a non-federated cluster before. If you have, the page should be easy to follow. If you have not setup a non-federated cluster before, I suggest doing so, before looking at this document. I think the document already has step by step instructions.I CONFIDENTIALITY NOTICENOTICE: This message is intended for the use of the individual or entity to which it is addressed and may contain information that is confidential, privileged and exempt from disclosure under applicable law.
