Oozie performance and usability improvements in Hue 3.10

Hello Oozie users,

We are really excited to announce several improvements for Oozie in the upcoming Hue 3.10 (~April ETA) that enhance its usability and robustness. Here is the new feature list.


**External Workflow Graph

** Hue supports workflow execution from Workflow Editor and File-browser. After submission, Hue takes the user to the Workflow dashboard page that shows the execution flow graph among other data. Earlier, this functionality was only supported when the workflow was submitted from the Editor. This feature enables us to see the graph for workflows submitted form File-browser as well as the ones submitted from CLI. Here is a video that demonstrates this.


**Single Action Execution

** This feature enables you to execute actions individually after a workflow is saved. Using the play button at the top right corner of an action, you can submit an individual action which helps you to test the correctness of your workflow.
