> I think the purpose of safemode is to guarantee that Ozone cluster is
ready to provide service to Ozone client once safemode is exited.
@ChenSammi I agree with that. I think the problem occurs with
OneReplicaPipelineSafeModeRule. This rule makes sure that atleast one datanode
in the old pipeline is reported so that reads for OPEN containers can go
through. Here I think that old pipelines need to be tracked separately.

> Currently, pipeline creation and destroy are synchronous operations. SCM
> directly connect to each datanode of the pipeline through gRPC channel to
> create the pipeline to destroy the pipeline.
> This task is to remove the gRPC channel, send pipeline creation and destroy
> action through heartbeat command to each datanode.
