> Project: Spark
> Issue Type: Bug

> A partition is of int datatype and a partition in legacy table was created as
> partition_name=partition_value
> Then, when we perform following operations,
> val df = spark.sql("select * from db.table");
> val modifiedDf = df.withColumn("partition_name", lit(2))
> modifiedDf.show(false)
> modifiedDf.write.mode(SaveMode.Append).insertInto("db.table")
>
> it throws error, even if spark.sql.sources.validatePartitionColumns=false.
