Dose additional dot in the domain is a valid domain

we want to build a new hadoop cluster ( ambari cluster ) , on redhat Linux machiens

our host-names are

master01.fg.sys70.com
master02.fg.sys70.com
master03.fg.sys70.com
worker01.fg.sys70.com
worker02.fg.sys70.com
worker03.fg.sys70.com

dose the additional "." in domain could be problematic when building a new hadoop cluster?

Solution

  • I currently maintain Hadoop servers that are named per environment

    For example 

    ambari.test.domain.com

    It works fine as long as your DNS services can resolve the addresses

    I suggest not calling something just master when building a cluster... Master of what? There's so many master services (Ambari Server, Namenode, HiveServer, ResourceManager, HBase Master, etc). If you have the available hardware, split each Hadoop service to individual machines and name them appropriately to that service.

    If something is only a datanode and nodemanager, feel free to name it "worker"
