Addendum and Erratum to "The MDS Queue: Analysing the Latency Performance of Erasure Codes"

In the above article [1] , we introduced two scheduling policies and analyzed their average job latencies. With an implicit assumption that the scheduling policies provide sample-path bounds by construction, we claimed that their average job latencies serve as upper and lower bounds on that of a centralized MDS queue. In this note, we present recently discovered counterexamples, disproving the assumption. We replace the assumption with a conjecture that the average latency bounds still hold. We also provide an erratum to the original article to correct any confusing or misleading statements.
