Hi all,
I run the tez-ui of master, and found couple of issues. Here's my
environment.
OS: Mac OS 10.9
Chrome
Tez master branch
*1. DAG Diagram View.*
- Is it possible to make the mouse as hand shape to indicate that
user can move the diagram.
- Does it make more sense to put Edge Source Class before Edge
Destination Class

- Sometimes the vertex info is too small that the right side info is
cut off

- The DAG diagram box is too small for complicated DAG, although I can
zoom in, but there's enough space to enlarge the diagram box.
- The vertex group is not clear. As least it should tell that
scope-37 is the vertex group name in the following screenshot. There's one
jira for visualize vertex group as sub graph (TEZ-1972) , maybe tez-ui can
use the same way to make the vertex group much clear

* 2. Topological order of vertex and order of task/taskattempt*
- We could sort the vertex by its id, the vertices have been
sorted in topological order when converting to DAGPlan
- Task & TaskAttempt also can be sorted by its id. Currently the
last started task/taskattempt is on the top.
* 3. Display issue of Task Panel*
The default number of showing task is 10, I have a dag with more
than 10 tasks. I change the number of rows to 25, it doesn't show 25 tasks.
I have to refresh page to make it work.
* 4. Recovery case issue*
- Task status may not be available due to lost of
TaskFinishedEvent (TEZ-2024)

- StartTime of Task is lost. It is because RecoveryService and
ATSHistoryLoggingService
are in different threads. The TaskStartedEvent may have been logged in
RecoveryService while it hasn't been put to TimelineService in
ATSHistoryLoggingService.

- Last application_attempt's task attempt info is lost in swimlane
in recovery. Not sure what kind of data swimlane use, but looks like it due
to AMContainerImpl is not recovered. (TEZ-860)
