Boyang Jerry Peng updated STORM-1507:
-------------------------------------
Description: When the parallelism of a component in a topology is changed,
the thrift APIs to get the parallelism ("get_parallelism_hint()") of components
still return the original parallelism of the component and not the parallelism
it changed to. This due to the fact that the thrift object responsible for
holding the information about a component only gets initialized once in
nimbus.clj but never gets updated when a change in parallelism happens. This
may also cause the UI to not display the correct parallelism as well. (was:
