Thanks for catching this. I'd prefer we make the change in PeriodicCheckpointer. That way, LDA with EM will still call PeriodicCheckpointer, which can handle persistence even if checkpointing is turned off. |

## What changes were proposed in this pull request? In the doc of [```checkpointInterval```](https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/param/shared/sharedParams.scala#L241), we told users that they can disable checkpoint by setting ```checkpointInterval = -1```. But we did not handle this situation for LDA actually, we should fix this bug. ## How was this patch tested? Existing tests. cc jkbradley Author: Yanbo Liang <ybliang8@gmail.com> Closes #12089 from yanboliang/spark-14298. (cherry picked from commit 56af8e8) Signed-off-by: Joseph K.
