ouch, we finally decided to make backward incompatible changes for
synonyms~~. That caused test case failure.
I adjusted the expected value according our new logic: always return
normalized similarity value for findSyonyms function
Also added defense code for potential divide by zero accordingly referring
to @srowen 's hot fix of another similar situation.
I have 90% confidence that these change is enough for passing tests.
The reason why I can't be 100%, is that spark sql can't compile and
run_tests script is not working in my local env. I hacked out the expected
value, but I verified it against before and after change.
FYI: the compiling issue on master branch about Spark SQL, not relevant to
our changes, but is a blocker somebody should look into.
