I have data frame in scala trying to save it into cassandra  where column data type in cassandra  is Map<text,text> . So when i try to save it am getting error as type mismatch 

val df_m=spark.sql(
      """select concat('{',"v_id'',':',v_id,',',''model_score'',':',model_score,',',''reserved3'',':',nvl(reserved3,'NULL'),'}')
        |as insight_meta_data  from model_scores """.stripMargin)

Result is {v_id:8888,v_score:9999,reserved3:Null}, i need result to be saved as {v_id:8888,v_score:9999,reserved3:Null} 

how i can save this string into data type: Map<text,text> in cassandra

type mismatch means expected output is not what it is. ex: result is stream and your expected output is Boolean

Expected output Map data type not Boolean
