-------------------------------
Summary: Improve the error message when unknown column is
specified in partition columns
Key: SPARK-23459
URL: https://issues.apache.org/jira/browse/SPARK-23459
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.0
Reporter: Xiao Li
{noformat}
test("save with an unknown partition column") {
withTempDir { dir =>
val path = dir.getCanonicalPath
Seq(1L -> "a").toDF("i", "j").write
.format("parquet")
.partitionBy("unknownColumn")
.save(path)
}
}
{noformat}
We got the following error message:
Partition column unknownColumn not found in schema
StructType(StructField(i,LongType,false), StructField(j,StringType,true));
We should not call toString, but catalogString in the function
`partitionColumnsSchema` of `PartitioningUtils.scala`
