Description

ECUnderReplicationHandler finds new target datanodes where replicas of an under replicated container can be added. However, it does not exclude datanodes that are pending addition of a replica of that container from the list of targets. Ideally, if we've already queued a command to add a replica to a DN, we shouldn't add another command.

This Jira investigates why datanodes pending adds aren't excluded. Is there a reason or is this a bug?
