Wei-Chiu Chuang commented on HADOOP-16955:
------------------------------------------
[~yuyang733] thanks for reporting the issue and offering the patch. Since we
are past 3.3.0 code freeze and that this patch is super big, I would suggest to
delay the fix to 3.3.1.
In the meantime, we can make release note to say cos is an experimental feature
with known issues that will be fixed in 3.3.1.
[~yuyang733] a few more feedbacks:
could you make the title of jira more clear? Given that you intend to fix
multiple unrelated issues, I suggest to make this jira an umbrella, and file
separate subtask jiras for each independent fix. That way, it'll be easier for
other folks to review.
[~sammichen] you've helped bring the initial version of cos cloud connector to
Hadoop. Would you be interested to working with [~yuyang733] to incorporate
this fix into Hadoop?
