[jira] [Updated] (SPARK-6925) Word2Vec's transform method throw
IllegalStateException if a word not in vocabulary, but findSynonyms(word:
String, num: Int) method neither try catch exception nor throw exception.
[ https://issues.apache.org/jira/browse/SPARK-6925?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen updated SPARK-6925:
-----------------------------
Priority: Minor (was: Critical)
I might be missing something, but isn't that expected behavior? what do you expect instead as the result of such an operation?
