Zhe Zhang updated HDFS-8120:
----------------------------
Attachment: HDFS-8120.003.patch
Thanks Jing for the comment on {{BlockManager}}. The 003 patch makes the
suggested change. I will add a new unit test in the next rev.
Also thanks for [~libo-intel]'s suggestion. I changed the variable name. I also
tried updating the {{writeParityCellsForLastStripe}} logic to use the new
{{getInternalBlockLength}} method to calculate the size of last parity cell,
but it caused test failures. You can look at the commented code in the method
to find how I tried. Could you take a look and suggest how to update it? I
think we should make the calculation consistent with the util class. Thanks!
> Erasure coding: created util class to analyze striped block groups
