Xi Shen updated SPARK-6706:
---------------------------
Comment: was deleted
(was: Yes, the {{collect()}} jobs finished, then hangs at the driver. Your
words are more accurate.
But I don't observe this behavior with the *random initialization* of k-means.
I think it is because the *kmeans||* algorithm has a more complex initialize
algorithm.)
> kmeans|| hangs for a long time if both k and vector dimension are large

> Project: Spark
> Issue Type: Bug
> Components: MLlib
> Affects Versions: 1.2.1, 1.3.0
> Environment: Windows 64bit, Linux 64bit

> When doing k-means cluster with the "kmeans||" algorithm which is the default
> one. The algorithm finished some {{collect()}} jobs, then the *driver* hangs
> for a long time.
> Settings:
> - k above 100
> - feature dimension about 360
> - total data size is about 100 MB
> The issue was first noticed with Spark 1.2.1. I tested with both local and
> cluster mode. On Spark 1.3.0. I, I can also reproduce this issue with local
> mode. **However, I do not have a 1.3.0 cluster environment for me to test.**
