Yes, the user arun issues a command hadoop fs -ls / Since ranger allows only 3 users as mentioned in the screenshot. arun should not be able to access / (in hdfs). but it is not the case

ranger-screenshot.pngI am using the default policy for HDFS provided after ranger installation. IT is not working as expected. this is my hdfs permission . Attached is the screeshot of ranger policy. now if an user arun is trying to access hdfs, he shouldnt be as only hadoop,rangerlookupuser and ambari-qa have the permissions as per the policy. Am i doing anything wrong. Or how do i restrict an user named arun using ranger. any thoughts would be grear hadoop fs -ls /

Hi @Sunile Manjee, you article is great. I tried following the same steps and was successful in creating a schema and a table within it. But if i try to drop the table, i see the error that "Table not found". And if i try to create the table, i see the message "Table exists". Any thoughts on it.

We are having a 10 dat node cluster. But data in hdfs is not spread across the nodes. some nodes are under utilized. Will a hdfs rebalancing activity resolve this issue. And During rebalancing will we be able to use the cluster.

We removed a host from our cluster by stopping all the services, stopping ambari agent on the host and then deleting the host from ambari. the deleted host had datanode, node manager and region server. But we see the regionserver as dead in the hbase master ui. even after multiple restarts of hbase. Just for a few mins after restart the region server(from the deleted host) is not shown as dead, again in a few minutes it is shown in the dead list. the other components like datanode and node manager doesnt show this behavior. any thoughts on how to clear this alert.
