> Per discussion in HDFS-8347, we need to support encoding/decoding variable width units
data instead of predefined fixed width like {{chunkSize}}. Have this issue to remove chunkSize
in the general raw erasure coder API. Specific coder will support fixed chunkSize using hard-coded
or specific schema customizing way if necessary, like HitchHiker coder.
