That's interesting. I patched your change to a clean checkout and simply
tested against the example on the JIRA. It throws the above exception.
val obj = (sqlSerDe._1)(dis, dataType)
if (obj == null) {
throw new IllegalArgumentException (s"Invalid type
$dataType")<===== this line
} else {
obj
}
I have no clue why it fails on my laptop. I can test on my own server
(ubuntu) tonight.
