@Arpit Agarwal Is this alert been introduced in Ambari 2.2.2 ? Just wanted to confirm that this has been happening and recent ambari upgrade exposed this behaviour.

We upgraded from HDP2.3 to 2.4 and Ambari from 2.2.0 to 2.2.2 and we started getting DataNode Heapsize alert. Although it is not causing any issues with the environment, would like to clarify few things : 1) Has this alert been introduced in Ambari 2.2.2 ? 2) Is HDP2.4 is expected to consume more heapspace then the previous versions ? Thanks Kumar

Our current environment is working with SSH authentication and there is a push to use Kerberos. Could someone explain what are the flaws with SSH authentication and what are the use cases for Kerberos Implementation

I am currently running HDFS rebalance in my prod environment and it has been running for more than 2 hours. How do I know the % of completion of this job ? I need to get an ETA on this one.

HDFS rebalance could be performed from command line or through Ambari UI. Which one do you suggest ? I would like to know the status of the rebalance or logs with error message in case if it fails

Data Center guys are taking down one of my data node for battery replacement. This maintenance is going to take 90 minutes. Through Ambari, i am going to put the node in the maintenance mode and bring down all the services. Is this sufficient ?

I have upgraded HDP from 2.3 to 2.4 in TEST environment and I see there is a change in spark between these versions. How can I get the list of jobs that uses spark currently ?

@mqureshi Kerberos is not enabled. Is it enough if I pull the users from the name node and admin node ?

Recently I was given an Hadoop Eco system to support. In this system, there is no Ranger, LDAP..etc etc..and the access was given directly to the boxes. Could you please suggest me some ways to get the list of users who uses our Hadoop System ?
