> {color:#172b4d}When a datanode dies and its containers go missing, calling
> *getContainerWithPipeline()* always results in an exception while the
> pipeline isn't available. To cover the case of dead datanodes, we should also
> be using *getContainer()* which checks only the SCM and if the container
> doesn't exist, throws an exception. {color}
> When cleaning up missing containers, their datanodes aren't available and the
> containers will be only deleted from the SCM. Recon's health task should pick
> up the change and remove the container from its tables.
> After trying to get a container along with a pipeline, also check just the
> SCM.
