[jira] [Updated] (SPARK-23459) Improve the error message when unknown column is specified in partition columns

     [ https://issues.apache.org/jira/browse/SPARK-23459?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xiao Li updated SPARK-23459:
----------------------------
    Description: 
{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:
{noformat}
Partition column unknownColumn not found in schema StructType(StructField(i,LongType,false), StructField(j,StringType,true));
{noformat}
We should not call toString, but catalogString in the function `partitionColumnsSchema` of `PartitioningUtils.scala`




  was:
{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`
