I created another Knox topology whose token has long TTL, and assigned it to NiFi. It's not SSO because Token is separated. I should type my username and password to Ambari even if I already logged in to NiFi. But at least I can logout from Ambari(and don't have to re-login to NiFi each 30 seconds). Thank you for all your help. ... View more

@gyadav I found that knoxsso.token.ttl was 10 hours. I set it 30 seconds and it worked. However, I want to set long TTL because I'm using other components which authenticates users by Knox only. If I set TTL 30 seconds, such components wil require login every 30 seconds. Is there a way like this? 1. make Ambari invalidate JWT not only its own session when I logout from Ambari 2. make Ambari authenticate users by Knox only(forbid to have its own session) Any information helps. ...

@Shu That works! Thank you for all you replies. ... View more

@Shu Thank you, I'll try that. The link isn't working. You meant this page? https://community.hortonworks.com/content/supportkb/193756/automatic-minor-compaction-on-hive-is-not-working.html And, do you have any idea to trigger ReplaceText and PutHiveQL only after some flowfile passed PutHiveStreaming? I think invoking minor compaction for each flowfile is too much when a lot of flowfile comes. ... View more

Hi @Akhil S Naik, The workaround works perfectly! Thank you for all your kindness. ... View more

Hi @Akhil S Naik, thank you for your reply. When I login as the user, I'm able to see the button. When I click it, at first it opens new tab for the File View URL, but redirects to the dashboard. When I input the File View's URL and access directly it goes well. So it seems the button's issue. The user's role is "NONE", and it has a privilege for Files View inherited from its group. For now I don't give each user privileges because I wanna make it easy to manage. Should I give each user privilege if their role is "NONE"? The atattchments are screenshots of the setting for user and its group. I also checked the setting of Files view. The group is surely listed on "Grant permission to these groups". ... View more
