Subject Re: Re-evaluation of GSoC Final Evaluation Result ( Apache Htrace Kudu Backend )
Date Tue, 30 Aug 2016 19:46:48 GMT
Hi Colin,

I understand it is your responsibility evaluate summer project as well I
strongly believe the community need to know truthful is your evaluation
facts you put into that Google evaluation.
I also believe putting untruthful evaluation facts even far worse than
exposing someone's personal emails.

So I hand over to Kudu and HTrace communities to evaluate the stuff that I
wrote whether those are agree with facts you put into that my evaluation. I
believe those who in this list the have better understanding
of the technology can evaluate the facts of your evaluation against the
code and the JIRA we had those all discussions. I even put this thing,
knowing Apache Kudu and Apache Htrace
very much biased Cloudera backed communities does not meet Apache open
source standards by any means.

Even Google or Apache Organization GSoC Admins re-evaluate my evaluation or
not, I believe this will be a good incident Google or participating
Organization like Apache to evaluate their own mentors as well
and also mentors to be honest to GSoC program as well being honest when you
are filling that evaluation, rather you put false facts to prove why you
have failed the student. If the student does not meet standards required by
the program, It s your responsibility to fail the student but not by this
kind of untruthful facts. I am sorry to point your personal emails, but I
believe community need to know the truth which I believe I did mistake for
all workI did not posted publicly in this mailing list, otherwise you would
have never put untruthful facts as my evaluation.

I also suggest before you are going to fail a student, be honest to
yourself whether you have spent at least a hour per week with the student
meeting other Google and Apache mentoring standards, I truly believe mentor
is not some one who just ask for status. I also suggest as person who works
for Cloudera full time could do that kind of effort without putting some
serious commitment.

Hopefully this will shed some light on future GSoC students as well.
