Nanda kumar commented on HDFS-13360:
------------------------------------
Thanks [~Deng FEI] for reporting and working on this.
We cannot start {{HdslDatanodeService}} (DatanodeStateMachine to be exact)
before starting {{ObjectStoreRestPlugin}} as we might miss setting
{{ozoneRestPort}} in some race condition. Please refer to this comment for more
details.
We should also create {{DatanodeDetails}} instance in {{HdslDatanodeService}}
before starting {{ObjectStoreRestPlugin}}, {{DatanodeDetails}} is shared
between {{HdslDatanodeService}} and {{ObjectStoreRestPlugin}}. This was the
main reason behind the movement of {{DatanodeDetails}} creation to the
constructor of {{HdslDatanodeService}}.
More details here.
As you have mentioned the existing implementation breaks
MiniOzoneClassicCluster. We should think of a cleaner way to address this issue.
