             Summary: SQL - Hive writer should not require partition names to match table partitions
                 Key: SPARK-16178
                 URL: https://issues.apache.org/jira/browse/SPARK-16178
             Project: Spark
          Issue Type: Sub-task
            Reporter: Ryan Blue


SPARK-14459 added a check that the {{partition}} metadata on {{InsertIntoTable}} must match the table's partition column names. But if {{partitionBy}} is used to set up partition columns, those columns may not be named or the names may not match.

For example:

{code}
// Tables:
// CREATE TABLE src (id string, date int, hour int, timestamp bigint);
// CREATE TABLE dest (id string, timestamp bigint, c1 string, c2 int)
//   PARTITIONED BY (utc_dateint int, utc_hour int);

spark.table("src").write.partitionBy("date", "hour").insertInto("dest")
{code}

The call to partitionBy correctly places the date and hour columns at the end of the logical plan, but the names don't match the "utc_" prefix and the write fails. But the analyzer will verify the types and insert an {{Alias}} so the query is actually valid.
