I've noticed that the date format set by the Workflow Manager when creating a coordinator job seems to be wrong. This affects the Start/End date below the Workflow Path at the top of the configuration. Example: When I select the current date, it sets the following date/time in the text box:
"04/10/2018 03:55 PM"
When I now submit the coordinator job, the submit will fail and Oozie will complain about the date format in the log:
used by: java.lang.IllegalArgumentException: parameter [end] = [04/10/2018 03:55 PM] must be Date in UTC format (yyyy-MM-dd'T'HH:mm'Z'). Parsing error java.text.ParseException: Could not parse [04/10/2018 03:55 PM] using [yyyy-MM-dd'T'HH:mm'Z'] mask
So I guess this is a bug in the website of the Workflow Manager?
