   @showuon  any thoughts on why this is suddenly failing? I put this test in specifically to make sure we don't introduce any nontrivial performance regressions -- my impression was that we generally had a pretty wide margin between the actual runtime and the timeout when this test was first added

   @ableegoldman , yes, you're right. I didn't check the logs clearly. It looks like there's a bug in general assignor that assign the same partition to multiple consumers. I'll start to work on improving the general assignor. Thanks.
