Vinayakumar B commented on HDFS-8347:
-------------------------------------
I understand from the above discussion that {{chunkSize}} is not required for
coders for the encoding/decoding in general (atleast for RS and XOR) as its
done byte-by-byte.
I am okay to get rid of it from the schema.
Now {{cellsize}} has to be given in {{HdfsFilestatus}}, as its no more part of
schema and required for correct reading of striped contents of a file.
> Erasure Coding: whether to use the same chunkSize in decoding with the value
> in encoding

> Currently decode buffersize for Datanode striped block reconstruction is
> configurable and can be less or larger than chunksize, it may cause issue for
> Hitchhiker which may require encode/decode using same buffersize.
