@John Bowler The "Hive View 2.0" is available in Ambari from Ambari 2.5 onwards (You can get is in HDP 2.6 Sandbox). So please check your ambari version i suspect that it might be Ambari 2.4. . If you are using HDP 2.5 Sandbox then you will not find the Hive View 2.0 in it because , HDP 2.5 Sandbox ships ambari 2.4 which has only Hive View 1.0 and Hive View 1.5 (also known as hive-next view) . Regarding your query "WORKFLOW_MANAGER View" In Ambari 2.4 this view is not Auto Instantiated. So if you want to see that view in the drop down menu then you will have to navigate to following in Ambari UI Ambari UI --> Admin --> Manage Ambari --> Views --> "WORKFLOW_MANAGER" --> Click on "Create Instance" button. Now it will start appearing in the Drop down menu once you create the instance of this view. . . ... View more

@Mohit Varshney I just noticed that you added ["mail.smtp.ssl.enable":true] parameter in your SMTP protocol which is actually causing the issue. Please remove that property and then it should not cause the following error any more. For smtp.gmail.com that property is not at all needed. Caused by: javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection? at sun.security.ssl.InputRecord.handleUnknownRecord(InputRecord.java:710) at sun.security.ssl.InputRecord.read(InputRecord.java:527) . ...
