What are the problems in creating volume in mapr hadoop

Question

I want to create a volume(MyVolume) but it can not mount the volume. it says this error: Failed to mount volume MyVolume, Permission denied its permission is root and admin.how can I create a volume that comes to folder my cluster?

It sounds like the user you are logging in as doesn't have the right permissions. This link will help you set the permissions up correctly:

When starting a new cluster, I typically create a 'mapr' user and give him admin permissions with this command:

maprcli acl edit -type cluster -user mapr:fc

Hope this helps!
