Change Category: Operability

> passed

> Key: CASSANDRA-17870
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17870
> Project: Cassandra
> Issue Type: Improvement
> Components: Tool/nodetool
> Reporter: Saranya Krishnakumar
> Assignee: Saranya Krishnakumar
> Priority: Normal
>
> 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
