How to use

documentAssembler = DocumentAssembler() \
    .setInputCol("text") \
    .setOutputCol("document")

tokenizer = Tokenizer() \
    .setInputCols(["document"]) \
    .setOutputCol("token")

stop_words = StopWordsCleaner.pretrained("stopwords_iso","ta") \
    .setInputCols(["token"]) \
    .setOutputCol("cleanTokens")

pipeline = Pipeline(stages=[documentAssembler, tokenizer, stop_words]) 

example = spark.createDataFrame([["நீங்கள் என்னை விட நன்றாக இல்லை"]], ["text"]) 

results = pipeline.fit(example).transform(example)
val documentAssembler = new DocumentAssembler() 
            .setInputCol("text") 
            .setOutputCol("document")

val stop_words = new Tokenizer() 
    .setInputCols(Array("document"))
    .setOutputCol("token")

val lemmatizer = StopWordsCleaner.pretrained("stopwords_iso","ta") 
    .setInputCols(Array("token")) 
    .setOutputCol("cleanTokens")

val pipeline = new Pipeline().setStages(Array(documentAssembler, tokenizer, stop_words))
val data = Seq("நீங்கள் என்னை விட நன்றாக இல்லை").toDF("text")
val results = pipeline.fit(data).transform(data)
