Li Bo commented on HDFS-7545:
-----------------------------
Hi, Zhe thanks for your careful review, and I learn a lot about the community
development details. I have created a subtask HDFS-7729 and upload a patch.
Nits: I think all of them are fixed.
Logics:
1. I upload a patch(Codec-tmp.patch) which can do encoding and decoding
work. 5 small files are added and they don’t depends on other files.
This help us not blocked by codec related development.
2&3. A unit test is added. ClientProtocol.addBlock still exists some
problems in my environment. Please help check this.
4. add some comments
5. yes.
6. The newly added logic does not influence packet size.
7.The code is not tested because unit test is blocked by
ClientProtocol.addBlock(). I think you’re right. I have fixed it in new patch
on HDFS-7729.
