Github user WeichenXu123 commented on the issue:
https://github.com/apache/spark/pull/17014
@zhengruifeng `KMeans` regarded as a bugfix(SPARK-21799) because the
double-cache issue is introduced in 2.2 and cause perf regression.
Other algos also have the same issue, but the issue exists in those algos
for a long time and they related to `Predictor` so it is not so easy to fix, we
can leave them in here and do more discussion.
