----------------------------
    Target Version/s: HDFS-7285
              Status: Patch Available  (was: Open)

Initial patch to remove workarounds on client side. DN code will be included in next rev.

The logic of handling {{FETCHED}} and {{ALLZERO}} chunks is moved from {{initDecodeInputs}}
to {{decodeAndFillBuffer}} to handle scenario where some chunks are {{PENDING}} when first
missing block is detected.
