bq. MinID was a bit confusing as it seems to indicate "minimum id" - maybe use
dagId or dagIndex, vertexId/vertexIndex and something more meaninful for task?
- For tasks/applications wouldn't it be a bit confusing to pass 5_11/7_9_13 as
ID or index? The values are neither ID nor index.
- What might be a better name?
dagMinID was added considering "applications" that might have multiple DAGs.
- No web-service call should support cross-dag queries. A single dag id/index
is sufficient.
-- Yes, dagMinID accepts just one single id.
bq. Also, please use "!isEmpty()" instead of "size() == 0"
- Thanks will do that in patch 2.

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