Run the following command to configure environment variables:
source /opt/client/bigdata_env

kinit MRS cluster user

If the development user is a machine-machine user, run kinit -kt user.keytab sparkuser.

If the development user is a human-machine user, run kinit sparkuser.
Run the following command to connect to Spark Beeline:
spark-beeline
Run commands on Spark Beeline. For example, create the table test in the obs://mrs-word001/table/ directory.
create table test(id int) location 'obs://mrs-word001/table/';
Run the following command to query all tables. If table test is displayed in the command output, OBS access is successful.
show tables;
