@Berk Ardıç, I have seen this error when there is not enough free memory in the node. Can you try restarting the ambari agents in the nodes where you see this issue and try start/stop the service ambari-server restart Also, it will be good to check the output of 'free -m' Thanks, Aditya ...

@Naif Massoud, Do you have any ranger policies on the folder. Also check if any jobs are running which can change the permissions of the folder. For this question 'Is it possible to lock the directory /projects/hawpm that nothing can change its permissions until it's unlocked again?' You can create a policy in ranger with the permissions you want to set and give access to only users/group you want . Thanks, Aditya ... View more

@Jalender, Activity explorer password is not stored in plain text format. You can login to the node where Activity explorer is installed. Open the file ( /etc/smartsense-activity/conf/shiro.ini ) and find the password [users] admin = admin ---------> password [main] sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager securityManager.sessionManager = $sessionManager securityManager.sessionManager.globalSessionTimeout = 86400000 shiro.loginUrl = /api/login [urls] /api/version = anon /** = authc If you want to change the password, Go to Ambari -> SmartSense -> Configs -> Activity Analysis -> Password. Change the password and restart the services Thanks, Aditya ... View more
