Are you looking at this guide? http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/latest/Cloudera-Manager-Managing-Clusters/cmmc_HDFS_hi_avail.html This guide talks about configuring HDFS for High Availability. It does not talk about installation. Did you already add a cluster with services like HDFS and ZooKeeper configured? I assumed from your post that you had an existing cluster. You enable High Availability after you've created a cluster. If you don't have such a cluster, then add one and configure the desired services, then follow the High Availability guide. ... View more

Hi Nishan,   During the install wizard, there's a prompt for you to specify where you'd like the CM agent binaries to come from. It's on the same page that prompts you to select CDH version.

Unfortunately, host names with capital letters will always hit this problem. CM respects the original host name capitalization, but hadoop converts it all to lowercase.   You'll have to pick lowercase host names. You might also be able to change your agent.ini on each host to override the hostname to be the lowercase name, haven't tried that though.   Thanks, Darren ... View more
