i tried this with decimal value
val employee = List(Employee("anubhav", 20000.5))
val employeeRDD = cc.sc.parallelize(employee)
val employeeDataFrame = employeeRDD.toDF("name", "salary")
employeeDataFrame.printSchema()
employeeDataFrame.write
.format("carbondata")
.option("tableName", "carbon3")
.option("compress", "true")
.mode(SaveMode.Overwrite)
.save()
cc.sql("SELECT * FROM carbon3").show()
| name|salary|
+-------+------+
|anubhav| 20001|
+-------+------+
it seems like it is rounding off the values can you suggest something
