> Writing into partitioned Hive tables has unexpected results because the table's partitioning is not detected and applied during the analysis phase. 
> For example, if I have two tables, {{source}} and {{partitioned}}, with the same column types:
> {code}
> CREATE TABLE source (id bigint, data string, part string);
> CREATE TABLE partitioned (id bigint, data string) PARTITIONED BY (part string);
> // copy from source to partitioned
> sqlContext.table("source").write.insertInto("partitioned")
> {code}
> Copying from {{source}} to {{partitioned}} succeeds, but results in 0 rows. This works if I explicitly partition by adding {{...write.partitionBy("part").insertInto(...)}}. This work-around isn't obvious and is prone to error because the {{partitionBy}} must match the table's partitioning, though it is not checked.
> I think when relations are resolved, the partitioning should be checked and updated if it isn't set.
