shahidki31 edited a comment on issue #20793: [WIP][SPARK-23643] Shrinking the buffer in hashSeed up to size of the seed parameter URL: https://github.com/apache/spark/pull/20793#issuecomment-472730569 > @shahidki31 I'm also kind of confused by this test. I don't see how it would be affected by a random seed. But in retrospect I'm not sure about the assertions. In the test that fails, what is the clustering expected to be? seems like there is only one reasonable clustering into 2 clusters, of 3 and 2 elements respectively? @srowen This is an exceptional scenario in case of PIC. Actual result should be cluster size of 4 and 1. If we change to "degree" this test case pass. It seems when we use "random", PIC is not working well after the changes, might be the reason mentioned by @MaxGekk . Need to analyze further.
