-----------------------------------------
Hi [~sunilg],
Thanks for updating the patch, few nits
# As discussed earlier, we are depending on one of the feature of HistoryServer
to return the latest event. So it would be better to cover in our test case as,
if there is break in that feature our testcase can catch it. i.e to add
additional events modifying the queue / priority (may be one modification for
queue and other for Priority).
# ApplicationUpdatedEvent has overridden {{hashCode}} but not {{equals}}. In
the first place do we require to over ride the hashcode method ?
> Running applications information changes such as movequeue is not published
> to TimeLine server
