Prakash Ramachandran commented on TEZ-2780:
-------------------------------------------
[~Sreenath] still reviewing the changes, one quick question though. Why does
the polling class need to be a mixin? this has two disadvantages.
1. there can be only a single instance of the polling.
2. its tied to the type of controller it is used in.
IMHO it would be better if its not a mixin, instantiate it in init. and
depending on if polling is required, do a start/stop. if you are concerned
about code reuse across task/task attempts write a helper function that takes
in the required arguments.

> Add AM API for fetching realtime tasks info:
> - API endpoint : /ws/v2/tez/tasksInfo
> - Query Params:
> -- dagID: The complete dagID, (mandatory).
> -- vertexMinID: A comma separated list. vertexMinID = vertexIndex.

> -- limit: Maximum number of items to be returned (Defaults to 100).
> - If taskMinID is passed: All (capped by limit) the specified tasks will be
> returned. vertexMinID if present wont be considered.
> - IF vertexMinID is passed: All (capped by limit) tasks under the vertices
> will be returned.
> - If just dagID is passed: All (capped by limit) tasks under the DAG will be
> returned.
> - Data returned: complete task id, progress, status
> Modify table component to automatically update cell based on model change.
