Joseph K. Bradley updated SPARK-7529:
-------------------------------------
    Description: 
Check Java compatibility for MLlib 1.4. We should create separate JIRAs for 
each possible issue.

Checking compatibility means:
* comparing with the Scala doc
* verifying that Java docs are not messed up by Scala type incompatibilities 
(E.g., check for generic "Object" types where Java cannot understand complex 
Scala types.  Also check Scala objects (especially with nesting!) carefully.
* If needed for complex issues, create small Java unit tests which execute each 
method.  (The correctness can be checked in Scala.)

  was:
Check Java compatibility for MLlib 1.4. We should create separate JIRAs for 
each possible issue.

Ideally, checking compatibility means creating small Java unit tests which 
execute each method.  (The correctness can be checked in Scala.)
