Yi Liu updated HADOOP-11961:
----------------------------
Description: (was: Today, we have a discussion including [~zhz],
[~drankye], etc., also discuss in HDFS-8347.
Some coder like {{RS}} and {{XOR}} is linear, some have coding boundary like
HitchHicker. If the coder is linear, we can decode at any size, and we don't
need to padding inputs to *chunksize*, if the coder is not linear, the inputs
need to padding to *chunksize*, then do decode.
This interface is important for performance, and can save memory/disk space
since the parity cells are the same as first data cell (less than codec
chunksize). )
Assignee: (was: Yi Liu)
Summary: Add interface of whether codec has chunk boundary to Erasure
coder (was: Add isLinear interface to Erasure coder)
