Subject HDFS federation configuration
Date Thu, 23 Jan 2014 17:35:31 GMT

We tried setting up HDFS name node federation set up with 2 name nodes. I
am facing few issues.

Can any one help me in understanding below points?

1) how can we configure different namespaces to different name node? Where
exactly we need to configure this?

2) After formatting each NN with one cluster id, Do we need to set this
cluster id in hdfs-site.xml?

3) I am getting exception like, data dir already locked by one of the NN,
But when don't specify data.dir, then it's not showing exception. So what
could be the issue?

Thanks & Regards,
B Anil Kumar.
