It seems like this is happening because the default directory recommendations given contains /home as a mount point. What is the output of:

I still get this error. I repeat, I haven't given any values to the NameNode directories config, because I don't get an opportunity to do. Reloading the page or going Back then Next do not solve the problem for me.

I have opened https://issues.apache.org/jira/browse/AMBARI-12612 to fix this issue. The workaround is to either hit Back followed by Next. OR just refresh the page to get back the original config value.

Can you provide the output of 'ambari-server --hash' command? Also, do you see any Javascript exceptions? I have just attempted to reproduce the issue by adding HDFS service, but do not see the issue (screenshot attached). If you are not entering any /home value, and Ambari is not providing it by default, I am trying to figure out where it is coming from. <Screen Shot 2015-07-31 at 10.57.13 AM.png> What output do you see when you go to following URL in browser? http://[ambari-server]:8080/api/v1/clusters/[cluster-name]/configurations?type=hdfs-site<http://c6405:8080/api/v1/clusters/c1/configurations?type=hdfs-site> - Replace [ambari-server] with your Ambari server hostname - Replace [cluster-name] with your cluster ID - Make sure you are logged in Regards, Srimanth ________________________________ From: Ian Soboroff <[email protected]<mailto:[email protected]>> Sent: Friday, July 31, 2015 10:48 AM To: [email protected]<mailto:[email protected]> Subject: Re: Ambari 2.1.0 on HDP 2.3 problem deploying HDFS I haven't set the value of 'NameNode directories' to anything.

We show that error when it does - https://github.com/apache/ambari/blob/trunk/ambari-web/app/utils/validator.js#L96 (screenshot attached) What is strange in your case is that it does not show the text area so that you correct it. Can you detail the exact actions that resulted in this outcome? Alternatively, do you see any Javascript errors in the Javascript console, and have you tried it in other browsers?

I'm using Ambari to deploy, and so far have only installed Zookeeper and Ambari-metrics. When I go to install HDFS, I get to service customization, and it won't let me set a NameNode directory. I've attached a screenshot. When I hover the mouse over the 'NameNode directories' alert, the mouseover text says "Can't start with home(s)". At this point there is no way to proceed with the installation. Help! Ian <Screen Shot 2015-07-31 at 11.36.33 AM.png>
