Oleg Zhurakousky commented on YARN-1841:
----------------------------------------
Daryn
Unfortunately I still disagree and here is why. The API in question is a very
public API which one uses during the implementation of AM. The fact that it
behaves differently once invoked from the AM vs. just a simple API call to a
remote cluster is what I am questioning. Nothing stops me from doing the later.
Not a comment, doc, javadoc, warning message or anything else. In fact the
error message I see is completely misleading and took me on the wrong path of
figuring out the cause which resulted in this JIRA (which is different from
YARN-944). The current API is not designed in a way to help someone like myself
not to make such a mistake. So, from that perspective its still a problem and
while I won't be fighting over it by re-opening the issue, I would suggest to
rethink. Let's just say that I know a thing or two about the API design but I
also play for the same team (HWX) and while I am freely expressing my concerns
with good intentions, someone else may not have as much patience and fall back
to YARN alternatives (quite a few, depending on how you look). Anyway, I'll
leave it up to you.
Cheers
