> Issue Type: Bug

> Fix For: 1.4.0

>
> Today, container pipelines are cached in OM and the cache data consistency is
> eventually ensured by client behavior. This means, if a container is
> replicated to another set of datanodes, the client detects this change when
> using the outdated cached pipeline to read data from datanodes and requests
> OM to refresh the pipeline cache from SCM.
> When the datanodes belonging to a container go offline, there are chances
> that an empty pipeline could be cached in OM. However, when client get an
> empty pipeline, it fails to ask OM to refresh the pipeline.
