我在运行hive，但我出错了

Caused by: javax.jdo.JDOFatalDataStoreException: Unable to open a test connection to the given database. JDBC url = jdbc:derby:metastore_db;create=true, username = APP. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------
java.sql.SQLException: Failed to create database 'metastore_db', see the next exception for details.

在这里

Caused by: java.sql.SQLException: Failed to create database '/home/Desktop/metastore/metastore_db', see the next exception for details.
