Re: [DISCUSS] Graduate Apache HAWQ (incubating) as a TLP

[Lei Chang]

Hi Bertrand,

Some new PPMC members are not added to the page, now it is corrected.

Thank you for pointing this out.

Cheers
Lei

+1 (binding)

Been following the discussions and knowing the mentors I believe the team
can continue to improve and learn how the Apache way works.

None of them are affiliated with Baidu Inc., just initial committers are.

Are the mentors also affiliated with Baidu Inc.. ?

I had a look at
https://cwiki.apache.org/confluence/display/HAWQ/ASF+Maturity+Evaluation
- thanks for providing that BTW!

Do I understand CO40 correctly that only one PPMC member was added
during the incubation of HAWQ, since September 2015 ?

If yes that raises some alarms, can the mentors comment on that?

It's not "everyone" - Josh who's a Gossip mentor says:

You are right that some TLPs have little activity, but they also don't
use much volunteer energy beyond people who are involved in them.

Podlings, on the other hand, consume energy from the Incubator and
from its mentors, so we don't want podlings to stay inactive for long
- a podling needs to be working and growing towards graduation, to
make space for other podlings in a reasonable time.

Retiring from graduation does not mean failure - the Apache model does
not fit all projects and communities, there's no shame in continuing
work elsewhere if incubation is not progressing.

I don't know much about Gossip, speaking in general terms only.
