I have installed all my 3 nodes in MapR web installer successfully, but after opening up MCS I am unable to view all 3 of them. I am trying out exercises in the ADM200 lesson too.
One of them also has an error that it is unable to transmit a heartbeat. I have installed my nodes on Centos VM for practice. All of them have met the min requirements.
I have installed the Enterprise trial version as my company is considering to get one.
Pls help. Thank you!
