Liang-Chi Hsieh commented on SPARK-24465:
-----------------------------------------
I'm not sure if SPARK-12878 is a real issue. Seems to me that it just needs to
write nested UDT codes in the working approach.
> LSHModel should support Structured Streaming for transform
> ----------------------------------------------------------
>
> Key: SPARK-24465
> URL: https://issues.apache.org/jira/browse/SPARK-24465
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Affects Versions: 2.4.0
> Reporter: Joseph K. Bradley
> Priority: Major
>
> Locality Sensitive Hashing (LSH) Models (BucketedRandomProjectionLSHModel,
> MinHashLSHModel) are not compatible with Structured Streaming (and I believe
> are the final Transformers which are not compatible). These do not work
> because Spark SQL does not support nested types containing UDTs; see
> [SPARK-12878].
> This task is to add unit tests for streaming (as in [SPARK-22644]) for
> LSHModels after [SPARK-12878] has been fixed.
