Hi @marmbrus , this is a pretty common scenario in production, where the
data is generated in some directory and then later partitions are added to
tables using alter table <tablename> add partition (<col>=value) location
<directory where data is generated (where path does not contain partition
key=value)>
In the old parquet path in v1.2.1, this is not possible.
This is doable in the new parquet path in spark 1.3 though.
