Siddharth Wagle commented on HDDS-3104:
---------------------------------------
[~adoroszlai] I think this happens because:
1. HddsDatanodeService#stop, calls DatanodeStateMachine#stopDaemon which sets
the StateContext.state = SHUTDOWN
2. The DatanodeStateMachine is calling StateContext.execute because the stale
state it read
3. StateContext.excute will set shutDownOnError to true when it sees this state
even though there was no error
So, I have a proposed patch for this, attaching it here before making a PR,
would like to know your thoughts.
