Re-installing MapR - Will I lose data?

I'm a novice at MapR. I had a 3 computer cluster going and put some data into the nfs drive. I could take a look at the data using the command

 

hadoop fs -ls

 

 

Then I decided to upgrade the cluster, which went sideways. I'm afraid of proceeding further because I'm not sure that by uninstalling mapr-core, I'll lose the data I saved. Is it possible to remove and reinstall mapr and recover the old data?

 

Thanks!
