@Scharan thanks a lot for replying. The solution you suggested worked! But I just wanted to know whether modifying those two properties as you mentioned will cause any decrease in the security of my HDFS or cluster anyway?

Hi eveyone, Ambari :- 2.7.4.0 HDP :- 3.1.4.0 I want to know whether postgresql in addition to MYSQL ( I will be using MYSQL in advanced database configuration while setting up Ambari server as my choice ) is needed for Ambari ( 2.7.4 ) installation or not. If it is needed should I install it on both Ambari Server host and also Ambari Agent hosts or only Ambari Server host. On which hosts is it required? Please help! @KuldeepK @jsensharma @MattWho @Shelton

Hi everyone, Ambari :- 2.7.4 HDP :- 3.1.4.0 I had done the ambari installation using local repositories with no Internet access for Ambari and HDP as mentioned in the official docs by creating directory structure /var/www/html and, untarred all the HDP and Ambari files into /var/www/html/hdp and /var/www/html respectively, as mentioned in the docs. :- [ Ref :- https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/getting_started_setting_up_a_local_repository.html https://docs.cloudera.com/HDPDocuments/Ambari-2.7.5.0/bk_ambari-installation/content/setting_up_a_local_repository_with_no_internet_access.html ] Then, I used python's Simple HTTP Server to host my local repository by running the command `python -m SimpleHTTPServer 2000` from inside /var/www/ instead of using Apache HTTP server as mentioned in the docs, to host my repositories in html directory on port 2000. Installation was done and services are running fine. But the problem that I am facing is the / (root) partition of my system is now at 98% and these files of ambari inside the /var/www/html are taking up 11 GBs. So my question is as the installation is done and the services have been running for few days, is it possible to move all the files inside the /var/www/html into some other directory on my system (lets says /app) and create a directory /app/html and put all those ambari and HDP files inside it and then create a new python SimpleHTTPServer from /app as I did for /var/www/ to host the newly created html directory containing the copied files? What effects will it have, if any and is it safe to do that as my cluster is up and running? Is there any other way is this is not possible? Thanks in advance. Please help! @jsensharma @Shelton @nsabharwal

Hi everyone, I am new to Ambari and have just installed Ambar 2.7.4 with HDP stack 3.1.4 with a cluster having 1 node running the Ambari Server, one being the master node of all service components and there is one more. The installation completed with few warnings, all the services on the web UI are running with green light on. The problem is an alert that says.. SmartSense Bundle Capture Failure Last SamrtSense bundle was not successful. Bundle key.unspecified_xxxxxx_0_2020-10-04_02-00-01, status:failed Also, the Activity Analyzer stops again and again after restarting it. All other services are running. PS: I have just installed this and haven't loaded any data or anything or tested anything. Please provide help! Thankyou! @jsensharma @MattWho @Shelton @nsabharwal
