I am trying to save a dataframe as .csv in spark. It is required to have all fields bounded by "Quotes". Currently, the file is not enclosed by "Quotes".
I am using Spark 2.1.0
Code :
DataOutputResult.write.format("com.databricks.spark.csv").
option("header", true).
option("inferSchema", false).
option("quoteMode", "ALL").
mode("overwrite").
save(Dataoutputfolder)
Output format(actual) :
Name, Id,Age,Gender
XXX,1,23,Male
Output format (Required) :
"Name", "Id" ," Age" ,"Gender"
"XXX","1","23","Male"
Options I tried so far :
QuoteMode, Quote in the options during it as file, But with no success.
("quote", "all")
, replace quoteMode
with quote
or play with concat
or concat_ws
directly on df
columns and save without quote - mode
import org.apache.spark.sql.functions.{concat, lit}
val newDF = df.select(concat($"Name", lit("""), $"Age"))
or create own udf
function to add desired behaviour, pls find more examples in Concatenate columns in apache spark dataframe
