Cannot import data using neo4j-etl export

[AnoYuan]

My process is like this：
1.generate mapping.json
bash ./neo4j-etl generate-metadata-mapping --rdbms:url jdbc:mysql://mysql-ip:mysql-port --rdbms:user root --rdbms:password root --output-mapping-file "/var/lib/neo4j/mapping/test.json" --rdbms:schema test
2.Import data
bash ./neo4j-etl export --rdbms:url jdbc:mysql://mysql-ip:mysql-port/test --rdbms:user root --rdbms:password root --destination /var/lib/neo4j/data/databases/test.db --import-tool /var/lib/neo4j/bin/ --csv-directory /var/lib/neo4j/import --neo4j:url bolt://neo4j-ip:7687 --neo4j:user neo4j --neo4j:password 123456 --options-file /var/lib/neo4j/conf/options.json --force --mapping-file "/var/lib/neo4j/mapping/test.json" --debug

What should I do?

Can you stop your neo4j database before you start your ETL process?
Or use the online import mode.
