Not able to create Hive table from HDFS file

Question

I am trying to create a Hive table using a csv file which I have already stored in the hdfs. I am running the following command to do this:

CREATE EXTERNAL TABLE student (studentId String , email String, class String)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' 
LOCATION '/user/hadoop/student/student_data.csv';

When i run this, I am getting the following error:

MetaException(message:hdfs://PC:8020/user/hadoop/student/student_data.csv is not a directory or unable to create one)

You dont have to specify the file name to get data from because by default, Hive takes all the files mentioned in the path. So, you only have to mention the path to the file:

CREATE EXTERNAL TABLE student (studentId String , email String, class String)
ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' 
LOCATION '/user/hadoop/student/';
