I am using Cloudera Director and Cloudera Manager to create a new CDH cluster in AWS. I was looking over this document, "Cloudera Enterprise Reference Architecture for AWS Deployments", and it states that " Cloudera requires using GP2 volumes when deploying to EBS-backed masters, one each dedicated for DFS metadata and ZooKeeper data." I see that I can attach additional EBS volumes when creating the cluster in Cloudera Director, but once I have added 2 volumes, how can I choose to use one for DFS and one for Zookeeper?
Thanks, worked perfectly. I was able to easily change the directories for those configurations in the Cloudera Manager. As a note for anyone else looking into this, the owner of the /data/dfs/nn dir needs to be hdfs.hadoop and the owner of the /data/zookeeper dir needs to be zookeeper.zookeeper. I had to make the zookeeper directory manually and also needed to add the dir "version-2" inside the zookeeper directory manually.
