@yhuai You are right. This is not a good test case for verifying this. I
will add a case like
```scala
sql(
"""
|INSERT OVERWRITE TABLE table_with_partition
|partition (p1='a',p2) IF NOT EXISTS
|SELECT 'blarr3', 'newPartition'
""".stripMargin)
```
Actually, the above statement returns an empty result set, which is still a
wrong answer.
Regarding your follow-up question, I also realize this is another bug we
should capture, as shown above:
https://github.com/apache/spark/pull/13447#issuecomment-223409590. My original
plan is to submit a PR for addressing that issue after
https://github.com/apache/spark/pull/12313 is merged. If
https://github.com/apache/spark/pull/12313 will not be merged in this release,
I will do it now. Thanks!
