> Suppose we have defined a partitioned table:
> {code}
> CREATE TABLE src (a INT, b INT, c INT)
> USING PARQUET
> PARTITIONED BY (a, b);
> {code}
> We should check the partition columns when appending DataFrame data to existing table: 
> {code}
> val df = Seq((1, 2, 3)).toDF("a", "b", "c")
> df.write.partitionBy("b", "a").mode("append").saveAsTable("src")
> {code}
