-------------------------------------

             Summary: Empty DataFrame with spark.read.text() cannot be written as it has no fields
                 Key: SPARK-16006
                 URL: https://issues.apache.org/jira/browse/SPARK-16006
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Tathagata Das



Attempting to write an emptyDataFrame created with {{spark.read.text().write.text("p")}} fails with the following exception

{code}
[info] - text API *** FAILED *** (218 milliseconds)
[info]   org.apache.spark.sql.AnalysisException: Cannot use all columns for partition columns;
[info]   at org.apache.spark.sql.execution.datasources.PartitioningUtils$.validatePartitionColumn(PartitioningUtils.scala:355)
[info]   at org.apache.spark.sql.execution.datasources.DataSource.write(DataSource.scala:432)
[info]   at org.apache.spark.sql.DataFrameWriter.save(DataFrameWriter.scala:213)
[info]   at org.apache.spark.sql.DataFrameWriter.save(DataFrameWriter.scala:196)
[info]   at org.apache.spark.sql.DataFrameWriter.text(DataFrameWriter.scala:525)
{code}

This is because # fields == # partitioning columns  = 0 at org.apache.spark.sql.execution.datasources.PartitioningUtils$.validatePartitionColumn(PartitioningUtils.scala:355)
