Hello,

I have a 5 node cluster managed by cm and have cdh(4.6) and cloudera search(1.2) installed on all machines.Need to start and configure hdfs,zookepper,hbase,map reduce and solr with high availabity hdfs.Can some one help or point to a document on how to do this.

Also if I want to have DFS zk failover controller in two nodes how to go about this?

Hi Nishan,

Here's how you can find documentation:
1) go to http://www.cloudera.com/content/support/en/documentation.html
2) Click on your version of Cloudera Manager (4 or 5)
3) From the dropdown, select the correct minor version of Cloudera Manager, or the closest number to it.
4) Click on the Installation Guide
5) Look for your topic in the left, or use the search in the upper left. In your case, you can search for "High Availability" and you'll find the right document for turning on HDFS High Availability.

Thanks,
Darren

Thanks Darren.The guide combines CDH installation and starting of services.For me the issue is I have already completed my installation.Hence I am not able to get to that screen which allows you to start services.Are these two process tightly coupled?

1.CDH installation completed.How to start services from cm UI?

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.
