Changing Ranger UI password causing Namenode issues

bsaini — Fri, 23 Oct 2015 03:24:47 GMT

Changing Ranger UI password causes Namenode to stop because it seems that the password needs to be updated in HDFS plugin within HDFS config. However, I am not sure which config needs to be updated in HDFS plugin. Please advise.

If you have changed ranger admin password in Ranger UI, that needs to be updated in Ambari as well. Please update admin_password under Advanced ranger-env section.

Vel, thanks for the answer. Just because Neeraj has the screen snapshots (which will make it clearer for the next guys), I will select his answer as correct but I know you are the source for his answer too 🙂

@vperiasamy@hortonworks.com Can you explain what is "Ranger Admin user's password for Ambari"? I thought it was the password for admin user on ambari, but I tried to change it with new ambari admin's password and it breaks hdfs and hive services as well. I updated only "admin_password" with new Ranger admin password like Neeraj's screenshot and it worked.

Thank you.

@Guilherme Braccialli - For managing ranger repo's from within Ambari, an admin user is created the first time (default name is amb_ranger_admin - see Advanced ranger-env section). The field you are referring to is the password for this particular user.

Hello Neeraj, I tried changing the ranger admin password to "admin" in Ambari UI - Ranger - Config - Advanced Ranger Env.
However not able to access Ranger UI. Can you please advice if this password has to be changed any other place.
Thank you.
