File/Hadoop Csv Input Adapter Cannot Read File

Here is the problem:

I want to use to file/hadoop csv input adapter to load a test.csv file into the attached window. The following is the snap screen.

And the corresponding csv file is like this:




But, when I started the project, I found nothing in the window, and then I checked the adapter run-time information, and I found this:

It seems that the adapter read nothing.

I am sure that the dir path and file path is correct, and there is no errors printed on the console.

So, what should I do?

    You will find more information about the adapter run-time in the frameworkadapter.log file for the project. Since you are running the project in Studio's local cluster, the log file will be here:
