Hadoop components for admins

I haven't completed the admin course yet but want to shoot these questions out of curiosity.


I take it that admins will need to do a lot of work on installing, configuring, adding/repairing/removing nodes and HDFS - very obvious, almost 100% admin territory.


Understanding that devops/sysadmin need to understand the Hadoop as the whole system, should know how everything works together and get familiar with each component but .......


From the sysadmin/devops point of view, if experienced real world Hadoop admins ranked the ecosystem components in terms of admin frequency, importance, and needs for maintenance, how would it be?
