I'm trying to install Hadoop on Ubuntu as Windows subsystem, the installation is finished, but I'm getting error while starting Hadoop services.

$ start-dfs.sh
Starting namenodes on [localhost]
localhost: starting namenode, logging to /usr/local/hadoop/logs/hadoop-hduser-namenode-DESKTOP-HD9EL6C.out
localhost: nice: cannot set niceness: Permission denied
localhost: starting datanode, logging to /usr/local/hadoop/logs/hadoop-hduser-datanode-DESKTOP-HD9EL6C.out
localhost: nice: cannot set niceness: Permission denied
Starting secondary namenodes [0.0.0.0]
0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/logs/hadoop-hduser-secondarynamenode-DESKTOP-HD9EL6C.out
0.0.0.0: nice: cannot set niceness: Permission denied

I tried many solutions from different platforms, but nothing seems to work.

Any solution?
