from pyspark.sql.types import StructType,StructField,StringType,IntegerType
schema = StructType([StructField("id_code", IntegerType()),StructField("description", StringType())])
df=spark.read.csv("C:/Users/HP/Downloads/`connection_type`.tsv",schema=schema)
df.show();
+-------+-----------+
|id_code|description|
+-------+-----------+
|   null|       null|
|   null|       null|
|   null|       null|
|   null|       null|
|   null|       null|

Hi@khyati,

You are getting this type of output because of your schema. Just check the schema properly and then read the file. According to your output, it is reading only one column. So analyze your dataset first then use your commands.

After that it will work.

To know more about it, get your Pyspark certification today and become expert.

Thanks.
