Hi, @Cesar Rodrigues I upgraded my HDF 3.3 Now NiFi is 1.8. (1) was solved. I
don't found document about (2) yet. But it seems that PutHiveStreaming does not have compatibility
with Hive3 because directory stracture was changed from Hive2.

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.

@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.

Hi, I'm using Knox to login Ambari 2.7 and other components. I found that I can't logout from Ambari. When I click "Sign out" button, it redirects to Ambari's login view(/#/login), and then redirects to Dashboard.(/#/main/dashboard/metrics). Login state remains. How could I fix that?

@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.

Datas which are inserted into Hive by INSERT INTO command are gotten minor compaction. But the data inserted into Hive using NiFi's PutHive3Streaming aren't gotten minor compaction even if there is enough deltas. Is it possible to make minor compaction(NiFi) work?
