How to change zookeeper default directory during Ambari setup

[#1]

During the Ambari setup, Ambari is trying to create the home directory for zookeeper at /home/zookeeper. Because our network setup, I cannot use "/home" directory. How can I instruct Ambari to create zookeeper home directory to somewhere else, like /hadoop/zookeeper?

Here is the error message I got

This is not something where ambari needs to be instructed. From ambari, all it is doing is execurting the OS command - "useradd".
The useradd command of Linux create the directory at the default locaiton which is /home.

I assume here that you are using the Linux mostly - RHEL or CentOS. If so, then in order to change the default directory location from /home to /hadoop, you need to edit the OS files - "/etc/default/useradd".

# cat /etc/default/useradd

GROUP=100
HOME=/home
INACTIVE=30
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=yes

The file "/etc/default/useradd" as seen from above has the default HOME directory location set as /home.

You can edit it to make it as

# vi /etc/default/useradd

GROUP=100
HOME=/hadoop
INACTIVE=30
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=yes

Hope this helps.

# cat /etc/default/useradd

GROUP=100
HOME=/home
INACTIVE=30
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=yes

# vi /etc/default/useradd

GROUP=100
HOME=/hadoop
INACTIVE=30
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=yes

Make any other default changes which you like.
