Review comment:
This particular test was just to add some coverage generally to the
initialize method but you're right, I am missing coverage for the actual case
from that thread which was really the `toString()` method so I'll add a test
for that as well. Playing around with the 0.12.x branch and the master branch
(which has the NPE fix in), the root problem seems that `toString()` hits a NPE
before `setConf()` is called. In that thread the user was in a scala repl so
`toString()` was getting called and the following fails in `0.12.x` but works
after the NPE fix.
```java
HiveCatalog catalog = new HiveCatalog();
catalog.toString() // call by the scala repl, runs into NPE in 0.12.0
```
I thought maybe the user could do a one-liner to get the conf set before the
repl tries to print but `setConf()` doesn't return `this`. (Should it return
`this`?)
