It actually does work but we get an error if we try and show the results of
the DataFrame. This is not good UX so we will need to fix.
```
>>> import ballista
>>> ctx = ballista.BallistaContext("localhost", 50050)
>>> ctx.sql("CREATE EXTERNAL TABLE orders STORED AS PARQUET LOCATION
'/mnt/bigdata/tpch/sf1-parquet/orders'")
<ballista.DataFrame object at 0x7f501f088150>
>>> df = ctx.sql("SELECT count(*) FROM orders")
>>> df.show()
+-----------------+
| COUNT(UInt8(1)) |
+-----------------+
| 14999999 |
+-----------------+
```
