Yanbo Liang updated SPARK-10023:
--------------------------------
Description:
"checkpointInterval" is member of DecisionTreeParams in Scala API which is
inconsistency with Python API, we should unified them.
* checkpointInterval
** member of DecisionTreeParams <-> Scala API
** shared param used for all ML Transformer/Estimator <-> Python API
Proposal:
"checkpointInterval" is also used at ALS but the meaning for that is different
from here.
So we make "checkpointInterval" member of DecisionTreeParams for Python API.
Because it only validate when cacheNodeIds is true and the checkpoint directory
is set in the SparkContext, it not a common shared param.
