Joseph K. Bradley updated SPARK-24465:
--------------------------------------
Description:
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.
> LSHModel should support Structured Streaming for transform
