Hello.

I've installed Pentaho Server 8.0 CE on Linux Ubuntu 16.04 Server.

When I am trying to upload csv file to the server over browser on my local machine:
File -> Manage Data Sources -> New Data Source -> CSV File
and selecting valid csv file from my local PC after pressing "Import" button I am receiving "UploadFileServlet.ERROR_0005 - An error occured while uploading the file UploadFileServlet.EROR_0010 - File name is invalid."

The same file has been correctly processed on Pentaho Server 7.1 CE.

Server log shows the following error:
ERROR [CsvDatasourceServiceImpl] java.io.FileNotFoundException: /home/user/pentaho-server/pentaho-solutions/system/metadata/csvfiles (No such file or directory)


Does anybody have the same error and know how to fix this?

Thanks.
