I would like to add a custom alert for single or multiple nodes in the cluster apart from hadoop services which are already defined under "Alert" section of Ambari. I know that we can do this using Nagios however just wanted to know if it is possible via Ambari? e.g. I would like to monitor disk space of my /xyz directory which contains input data to some hadoop job.

@Sergey Orlov - As per error given in question FAILED:HiveException java.security.AccessControlException:Permission denied: user=tech_dmon, access=WRITE, inode="/user/p/data":tech_p:bgd_p:drwxr-xr-x Could you please confirm if inode name is /user/tech_p/data or its /user/p/data ? In any of the above case, you are running your oozie cordinator/workflow as tech_dmon user and its trying to write into some other user's user directory in HDFS instead of /user/tech_dmo/ hence you are getting permission denied error. Could you please check application logs of this job and let me know what is the value of below properties
user.name mapreduce.job.user.name
