Anu Engineer commented on HDDS-242:
-----------------------------------
# Should we fire an event if there node transitions from Stale/Dead to healthy
? , since we don't use it now, maybe leave a comment ?
# We need to integrate -- (Not as part of this patch, just an observation) To
SCMDatanodeHeartbeatDispatcher.
## – Command Status
## – ActionRequired
## – Pipeline Reports
# Eventually I would like to move the NodeHandler Section in
StorageContainerManager to its own static class. We can pass the EventQueue to
that Class. That way the call in StorageContainerManager will be
initEventHandlers()
#There is a bunch of CheckStyle issues.
