    workflow_configuration

    Type Description
    NebulaGraph Configuration The access address of the graph service that executes a graph query or to which the graph computing result is written. The default address is the address that you use to log into Explorer and can not be changed. You can set timeout periods for three services.
    HDFS Configuration The HDFS address that stores the result of the graph query or graph computing. Click Add to add a new address, you can set the HDFS name, HDFS path (fs.defaultFS), and HDFS username. You can configure the save path, such as hdfs://192.168.8.100:9000/test.
