Subject [jira] [Created] (AMBARI-15601) HA Namenode Move failed on Delete disabled NameNode+ZKFC stage
Date Mon, 28 Mar 2016 16:30:25 GMT
Aleksandr Kovalenko created AMBARI-15601:

             Summary: HA Namenode Move failed on Delete disabled NameNode+ZKFC stage
                 Key: AMBARI-15601
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.0.0
            Reporter: Aleksandr Kovalenko
            Assignee: Aleksandr Kovalenko
            Priority: Critical
             Fix For: 2.2.2

# On Nn ha environment, nn1 is on host1 and nn2 is on host2
# Put host1 in maintenance mode 
# Start "Move namenode wizard"
# Wizard will fail on last step "Delete disabled namenode+zkfc" because the namenode to be
deleted which was in maintenace mode never stopped as part of wizard, and delete operation
on a component in 'STARTED' state throws an exception
# user ends up with 3 instances of namenode.

It is reasonable to expect that the source host is in maintenance mode (the user is likely
doing a move because the host is in bad state).
All move wizards should tolerate the source host being in maintenance mode and just work.
