Zeppelin Notebook Install error

[#1]

I m trying to install hdp 2.5 in my cluster , I lanched the wizard Ambari 2.5 and everythings was okey untill Ambari gets to installing services and in the last part of installation I got this error of permissions with zeppelin notebook:

raise ExecutionFailed(err_msg, code, out, err)
resource_management.core.exceptions.ExecutionFailed: Execution of 'echo spark_version:1.6 detected for spark_home: /usr/hdp/current/spark-client >> /var/log/zeppelin/zeppelin-setup.log' returned 1. su: warning: cannot change directory to /home/zeppelin: Permission denied
-bash: /home/zeppelin/.bash_profile: Permission denied
-bash: /var/log/zeppelin/zeppelin-setup.log: Permission denied

I tried to create this directories /var/log/zeppelin and associte permission to user zeppelin but I still get the same error.

what should I do??

Are you running this as root user?

solution in two lines of code:

sudo chown -R zeppelin:zeppelin /var/log/zeppelin/
sudo chown -R zeppelin:zeppelin /home/zeppelin
