I am also curious about the answer.

If you grep the code, you will notice SO MANY python/shell script hard code the absolute path
/var/xxx  /usr/xxx .  Not everyone can install software under /

Subject: Manual install locations for Ambari, HDFS and HBase

I am trying to setup a hadoop cluster using custom locations. My root fs does not have enough
storage, but I have a large ephemeral storage disk that I could mount and use for installing
Ambari and HDFS, HBase.

Is there a configuration setting in Ambari that can help me move all Ambari+Hadoop related
storage (Ambari scripts, configs, logs, HDFS, HBase, Zkpr data, etc.) into  separate drives
(for eg., /hadoop, /hbase, /ambari, etc.).

I know it works when building HDFS and HBase from Apache sources and customizing the installation.
But I updated all the settings in step "Customize Services" in Ambari but still see Hadoop
conf directories missing and Ambari scripts running from /etc, /var etc. Is there a central
root.dir setting for each of these services (ambari and services deployed by ambari) that
can help me update the locations?
