Tom White commented on MAPREDUCE-2455:
--------------------------------------
> In fact, I'd go further and actually consider removing this api.
I agree with the sentiment. ClusterStatus shouldn't be used as a monitoring
API, since metrics (or other monitoring systems) should be used for that
purpose. In particular, the API that ClusterStatus (or ClusterMetrics in the
new API) exposes doesn't fit with MAPREDUCE-279. It's premature to remove them
in 0.23, but it makes sense to consider replacements for them.
Of course, we still need this JIRA to move forward with MAPREDUCE-1638 and the
code organization for MAPREDUCE-279.

> MAPREDUCE-2337 deprecated getJobTrackerState() on ClusterStatus, this issue
> is to remove the getter (in favour of getJobTrackerStatus(), which will
> remain) so there is no longer a direct dependency of the public API on
> JobTracker. This is for MAPREDUCE-1638.
