yes of course!
I deleted accumulo 2.0.1 and installed accumulo 1.10.1.
Then edited the conf/ files. I think I didn't do that right before.
And then it worked.

According to the Hadoop getting started guide (https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/SingleCluster.html) the resouce manager runs at: http://localhost:8088/
Can you run hadoop commands like:
> hadoop fs -ls /accumulo (or whatever you've decided on as the destination for files)
Did you check that accumulo-env.sh and other configuration files have been set-up for your environemnt?
