Jason Lowe commented on MAPREDUCE-3913:
---------------------------------------
Problem may have been introduced with MAPREDUCE-3754. Ajax data URL was
designated as cluster/apps/json but anything after cluster/apps/ is interpreted
as an application state.
Not sure the Ajax support is useful anymore, as the app table always is sorted
on the client and therefore the client always grabs all the data from the
server. Seems like we could just drop the Ajax loading support and leverage
the existing JS_ARRAY rendering and end up with the same thing.
