    I see a few possible issues with the most immediate being the path you are specifying for the CSV files you are trying to access with the input and output adapters. The file paths have to be:

    1) Relative to the streaming server

    2) Located within the sandbox directory of the streaming server.

    Since you are running SDS, the server will be on a Linux host. Even if you are using SDS with HANA Express (HXE), then the server is running in a Linux virtual machine. The paths you are using indicate that you are asking the adapters to read from a directory on a Windows machine, which will not be accessible from the server.

    We have a tutorial available that includes using a File/Hadoop CSV Input adapter that would probably be helpful in getting you started:

    The lesser issue is that the section of the log output that you included is for a DB Input adapter, but I don't see a DB Input adapter in the screenshot of your streaming project. Since there isn't a DB Input adapter in your project, that section of the log output won't be relevant to troubleshooting the current issue you are having.
