Hi, I need to get output like total-count-of-records-InTable, count(max(date)) using Hive. Where count(max(date)) ----> gives the count of records loaded from last run. Each record has current-run-date column. I know to get both separately, but not sure to get the output together... Could anyone help me on this... Appreciate your help.. Thanks, Jee

Hi Mahesh, There is no way to list all members of supergroup. But, we can run for individual user to see if they are belong to the group by using the below command. hdfs groups <username> Once again, thanks for time .

Is there any way to find it from ambari without logging to NameNode? If it is not, how to log on to the namenode from linux(edge node)? sorry for the trivial questiion. I tried to login from putty, i got exception.

yes. But, how to list all the users in the superusergroup? I found superusergroup : hdfs in hdfs-site.xml. But, how to find the users in the group hdfs.

Could you suggest me how to check on the namenode?

Hi Maheshwari, Our superusergroup is hdfs That's what i did. He asked me where i got these members from and i told from /etc/group file. But, Technical Lead said something different. Here is the conversation we had below. Jeeva:I got it from /etc/group file Fred: that is correct for this particular server how about what namenode? that's where 'hdfs groups' tell you

Hi Namit Maheshwari, Thanks for your time to reply. Your answer saved my life and one more question How to see the members of the superusergroup for a namenode? In my case, the super user is "hdfs". I have been asked to find all the members of the superuser group. /etc/group file is not for the namenode. So, there should be some other way.

Hi everyone, The logs are already displayed in the audits tab. The reason why i could not see is because of the"EventTime". The EventTime and Updated Time are not synced. That's why it is not showing the correct screen(i.e., latest logs). Then,i filtered logs based on source type and i could see my logs. However, I am getting different issue. Thank you guys for your time.
