--------------------------------------

Thanks [~leftnoteasy]

Some comments

1.
{code:java}
113     tensorboardDockerImage = parsedCommandLine.getOptionValue(
114     CliConstants.TENSORBOARD_DOCKER_IMAGE);{code}
In above segment, we have to handle default case also, correct ?

2. In {{updateParametersByParsedCommandline}}, 
{{setWorkerResource(workerResource)}} is removed, is this intentional?

3. 
{code:java}
467     // Add tensorboard to quicklink
468     String tensorboardLink = "http://"; + YarnServiceUtils.getDNSName(
469     parameters.getName(), TaskType.TENSORBOARD.getComponentName(), 0,
470     getUserName(), getDNSDomain(), 6006);{code}
Could we make *http*, *6006* etc from some common config end point or from 
default constants.

4. I think we can publish tensorboard link in all cases when user asks for 
tensorboard. May not need to check for verbose.

Tests looks good to me. Thank you.
