Hi Alan,

In Wink, you voted +1, and in Chukwa, you voted -1.  While the status are
similar between Chukwa and Wink, but what is the logic behind your votes?
 In addition, Chukwa and Kafka are similar, and some Kafka design are
borrowed from Chukwa.  Does your relationship with Kafka influence your
judgement being bias toward Chukwa?

You called me a lone developer, while the jira list showed there are
several others contributing as well.  There are people submitting patches
and open jira for discussions.

You volunteered to work as mentor for Chukwa, but we only hear from you 4
times while being Chukwa mentor:

1. March 23, we welcome you to become Chukwa mentor.  On the same day, you
ask Chukwa to be retired.
2. June Report, Chris reviewed report, you gave a +1.
3. September 9, you said "thank you" to Bernd for follow up on granting new
committers access.
4. Nov 16, you start on the private list on the same thread about retiring

I am sorry, but I may be blunt.  I think your action is harmful to Chukwa
community rather than helping the community.

In the Chukwa private mailing list, I also expressed my limitation to be
contributing to Chukwa while I am working through logistics with my
employer to get approval.  While I did not write new code for Chukwa for
the past half year, Chukwa continue to receive patches from the following

Noel Duffy
Jie Huang
Sourygna Luangsay
Abhijit Dhar
Saisai Shao
Ivy Tang
Prakhar Srivastava
Eric Speck

Some patches are committed by Ari Rabkin.  Contributions after 0.5 release
can be tracked in CHANGES.txt.  Chukwa is truly running as an open Apache
project where patches are reviewed and discussed.

Chukwa is used by Netflix, IBM, Intel, and several companies.  If you
search on LinkedIn, number of people that has Chukwa on their resume grown
from 30 people in January to 55 now.  The information are the same
information that I provided on chukwa-private mailing list.

Here is the quote from Chris:

"Eric, you recommend graduating Chukwa to be a TLP based on its
activity relative to other incubator projects, engagement from
independent contributors, adoption and investment in commercial
offerings, and indirect measures of a growing interest in the project.
Is that a fair summary?"

While Chukwa community is low key on participate political votes because
the same rehash of closing the community has been on the focus since the
original incubation proposal was written.

If we are going to move forward, more time in incubation is not a realistic
option.  The only way is vote for graduation and avoid the vicious cycle of
closing the project review.
