I just started using Cloudera Manager to build my new hadoop cluster, its
neat !

Here are the issues I am facing.

Using the default install, everything went fine. When I do a "hadoop fs -ls
/" , I see the root file system of the datanodes ?

Did I miss anything ?
How do I modify the hdfs-site.xml ? There are three locations of it, so
which one should I modify in order that Cloudera Manager picks up the
modified file and pushes the change into the cluster.

Thanks in advance

Steve

Hi Steve,

Since this is not relevant to the Apache Hadoop HDFS user lists, I'm
moving it to the SCM-users list which relates to Cloudera Manager
usage. Also find my response inline.

Good to know! We also welcome all sorts of feedback :)

You may be missing the step at
https://ccp.cloudera.com/display/express37/Generating+Client+Configuration
which is required for all clients you want to allow access to the
cluster. You can place this at /etc/hadoop/conf and that should work.

Do not modify the configs managed by CM, they are for daemons/services
alone; Whereas a generated set of configs are a subset of only
necessary configs required by clients.

Steve,
You need to download the Client Configuration from Cloudera Manager
and deploy them to the nodes...

At least that's what I did....

You'll get better support at Cloudera forums, not the ASF ones.
