the current version of evtsender are initialized by signalman with fixed destination. in order to change destination, they somehow change the destination by themselves because they are all independent processes. but if the destination is given by framework, hbasf2 will be more flexible.

this feature will change the interface so that the framework feeds the destination to evtsender. evtsender will initialize socket by referring the destination for every single operation. this might cause some overhead but i expect the overhead is not so high.
