> Currently, if the client reads from all Datanodes in the pipleine fail, the
> read fails altogether. There may be a case when the container is moved to a
> new pipeline by the time client reads. In this case, the client should
> request for a refresh pipeline from OM, and read it again if the new pipeline
> returned from OM is different.
> This behavior is consistent with that of HDFS.
