So I just very recently installed HDP 2.3.4.0 using the Ambari Install wizard and a local repository. I installed on 5 nodes according to default/suggested options on the wizard. This is my first experience with the Ambari and HDP environment, so I am a bit lost. After a bit of bug fixing, all of the services are running (dashboard-aug31.png) on all 5 nodes, with no alerts. Yet, the widgets all say n/a or infinitely load, and all of the views are empty with messages like "cluster not connected", "NullPointerException", etc. Obviously there is a large flaw in my setup, and I don't know how to figure out what it is or how to fix it. I can't find anyone posting as to having the same thing happen to them. Does anyone have any ideas? I haven't started actually using it yet, so there is no data anywhere. Here are screenshots of the views: yarn-queue-manager.png smartsense-view.png hive-view.png tez-view.png ... View more

So I've just completed the Ambari install wizard (Ambari 2.2, HDP 2.3.4) and started the services.Everything is running and working now (not at first) except for 3/5 hosts have the same issue with the Accumulo TServer. It starts up with the solid green check (photo attached) but stops after just a few seconds with the alert icon. The only information I found about the error is "Connection failed: [Errno 111] Connection refused to mo-31aeb5591.mo.sap.corp:9997" which I showed in the t-server-process. I checked my ssh connection and its fine, and all of the other services installed fine so I'm not sure what exactly that means. I posted the logs below, the .err file just said no such directory, and the .out file is empty. Are there other locations where there is more verbose err logs about this? As said, I am new to the environment. Any general troubleshooting advice for initial issues after installation or links to guides that may help would also be very appreciated.
