I am using MapR Installer via web portal. All steps are done as instructed before node verification.

The node verification stage failed with an error that "mapr" is not in "sudoer" first. After adding "mapr" to "sudoer" by

$ sudo adduser mapr sudo

the following error appears. I could not understand this error. You help is highly appreciated. Thanks for reading my question.
