Spark beeline: table was created at default database even though specifing a database name

After running this command as follow:
${SPARK_HOME}/bin/beeline -u jdbc:hive2://192.168.156.5:10001/mydb -n mr -e "create table test_1(id int ,name string) row format delimited fields terminated by ',' stored as textfile;"
I found the table "test_1" was create at default database other than mydb database that i specified。
