Hey Guys, We did the necessary changes and were trying to get this back on track, but hit another wall,
we have two Clusters in Different DC ( DC1 and DC2) with cluster names ( CLUSTER_1, CLUSTER_2) we want to have a common analytics cluster in DC3 with cluster name (CLUSTER_3). -- looks like this can't be done, so we have to setup two different analytics cluster ? can't we just get data from CLUSTER_1/2 to same cluster CLUSTER_3 ? thanks anishek On Mon, Mar 21, 2016 at 3:31 PM, Anishek Agarwal <anis...@gmail.com> wrote: > Hey Clint, > > we have two separate rings which don't talk to each other but both having > the same DC name "DCX". > > @Raja, > > We had already gone towards the path you suggested. > > thanks all > anishek > > On Fri, Mar 18, 2016 at 8:01 AM, Reddy Raja <areddyr...@gmail.com> wrote: > >> Yes.
