Description

Observations (When vertex, task & attempt details are not available):

1. All the tables will just display a “No records available!” message, and work as expected. But
2. Graphical and swimlane views will cause error.
3. Stats in DAG details page will be displayed with all vertex/task counts 0.

Expected behavior:
When ever data is not available, all pages must display a “No {} available!” message. Where recordType could be Vertices, Tasks, Task Attempts etc...

• When ever vertex data is not available in DAG details page, display a "No vertices available!" message.
• Stats table in DAG details page must be hidden when vertex data is not available.
• Data not available messages must be displayed in Graphical and swimlane views when required.
