@marmbrus can you please provide a complete example that can execute in
`spark-shell`?
You can find a standalone runnable example with complete shell output in
[this gist](https://gist.github.com/ssimeonov/72c8a9b01f99e35ba470). Here is
the summary of what happens:
```scala
// ERROR RetryingHMSHandler:
MetaException(message:NoSuchObjectException(message:Function default.first does
not exist))
// INFO FunctionRegistry: Unable to lookup UDF in metastore:
org.apache.hadoop.hive.ql.metadata.HiveException:
MetaException(message:NoSuchObjectException(message:Function default.first does
not exist))
// java.lang.RuntimeException: Couldn't find function first
ctx.sql("select first(num) from test_first group by category").show
// OK
ctx.sql("select first_value(num) from test_first group by category").show
```
Perhaps the difference is that I'm using `HiveContext`?
