Ajay Kumar commented on HDDS-298:
---------------------------------
Ping [~ljain],[~elek] for review. Below is brief summary of
getContainerWithPipeline current state now.
* Return a pipeline if it exists already in PipelineManager#pipelineMap
* else
** if it is Open containers allocate new pipeline. (i am not sure if this is
correct)
** If closed reconstruct a pipeline using node replicas.
> Implement SCMClientProtocolServer.getContainerWithPipeline for closed
> containers

> As [~ljain] mentioned during the review of HDDS-245
> SCMClientProtocolServer.getContainerWithPipeline doesn't return with good
> data for closed containers. For closed containers we are maintaining the
> datanodes for a containerId in the ContainerStateMap.contReplicaMap. We need
> to create fake Pipeline object on-request and return it for the client to
> locate the right datanodes to download data.
