Thanks for the quick response.
Let me rephrase the question which I admit wasn't clearly worded and
perhaps too abstract.
To read a CSV i am using the following code (works perfectly).
SparkSession spark = SparkSession.builder()
.master("local")
.appName("Reading a CSV")
.config("spark.some.config.option", "some-value")
.getOrCreate();
Dataset<Row> pricePaidDS = spark.read().csv(fileName);
I need to read a TSV (Tab separated values) file.
With Scala, you can do the following to read a TSV:
val testDS = spark.read.format("csv").*option("delimiter","\t")*
.load(tsvFileLocation)
With Python you can do the following:
testDS = spark.read.csv(tsvFileLocation,*sep="\t"*)
So while I am able to read a CSV file, how do i read a "tsv" {tab separated
file}. I am looking for an option to pass a delimiter while reading the
file.
Hope this clarifies the question.
Appreciate your help.
Regards,
