Kai Zheng updated HDFS-8382:
----------------------------
Description:
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.
Update: per discussion in this issue, this will also remove {{initialize}}
method from erasure coders. The necessary initialization work will be done in
constructors.
