> During expansion by Dc, when we issue nodetool/rebuild from new dc to rebuild the data from other DCs. If src-dc is not passed explicitly, then C* tries to rebuild the data from the same (new dc) dc. 
> We don’t exclude other nodes in the same DC. Only down sources and the local node itself are excluded.
> ```
>  // We're _always_ filtering out a local node and down sources
>         addSourceFilter(new RangeStreamer.FailureDetectorSourceFilter(failureDetector));
>         addSourceFilter(new RangeStreamer.ExcludeLocalNodeFilter());
> ```
> We should fix nodetool/rebuild to exclude the local DC (from where we’re executing the command) while issuing nodetool/rebuild without passing src dc
