Why is MapR-FS consuming all available memory?

Hello All,

I am new to 'Admin' area. I have a 3 node cluster with MapR M3 edition. MapR FS is installed on first node.

I am facing memory consumption issue on first node after starting MapR services. I am not able to see any information on MapR management console, its just empty web page.

 

Below are some details which might help to get more understanding on the issue :

# clush -a free -m
