Issues with Hadoop under Windows

Beitrag von Tobias Hofmann »

Hi all,

I tried to get the provided Hadoop example code from exercise 2 running but I keep getting a java.lang.NullPointerException error directly after executing the job.
A friend of mine who is using Mac OS did not run into this error although he performed the same steps as I did.

Somehow I assume that this error has to do with Windows and that Windows is not able to create the directory where the output will be put in.

Has anyone of you managed to get the sample code running on Windows?
I would appreaciate any help. Thanks!

Kind regards
Tobias

Addition: Just wanted to confirm that this issue is definitely related to Windows. I tested it on my Linux VM and it worked without any issues.

Hi,

I think it is definitely related to Windows. We had similar issues in the past (https://d120.de/forum/viewtopic.php?f=591&t=34250)

Best,
Matthias
