Summary: Saving and loading HashingTF leads to hash function
changed
Key: SPARK-31668
URL: https://issues.apache.org/jira/browse/SPARK-31668
Project: Spark
Issue Type: Bug
Components: ML
Affects Versions: 3.0.0, 3.0.1, 3.1.0
Reporter: Weichen Xu
If we use spark 2.x save HashingTF, and then use spark 3.0 load it, and then
use spark 3.0 to save it again, and then use spark 3.0 to load it again, the
hash function will be changed.
This bug is hard to debug, we need to fix it.
