[ANNOUNCE] Weekly Community Update 2019/28

[Konstantin Knauf-3]

Dear community,

happy to share this week's community update with news about a Flink
Ecosystem website, new Jira permissions, Apache Flink 1.9.0 and a few more
topics.

As always, please feel free to add additional updates and news to this
thread!

Flink Development
===============

[ecosystem] Daryl and Robert have pushed the first version of a *Flink
ecoystem website* [1] to a staging environment for public testing. The
website will contain a catalog of community maintained Apache Flink
packages (e.g., connectors, metrics connectors, tooling, ...), which will
be an easy way to share one's work with the wider community. Currently,
Daryl and Robert are looking for feedback on the corresponding thread [2]
or github project [3].

[development process] Following our new contributions guidelines [4], the*
Jira permissions *have been changed so that only committers can assign
users to tickets. The discussion in the original thread has moved to the
topic of how to deal with the existing set of about 600 contributors in our
Jira project. [5]

[development process] It seems the discussion around initial *bylaws for
Apache Flink* has pretty much converged already. Expecting a vote to start
soonish unless new points are raised [6].

[releases] Gordon has prepared a RC0 for *Apache Flink 1.9.0* [7]. There
will not be a vote on this release candidate. It is merely a reference
point for ongoing release testing. To follow the release testing efforts
checkout this Kanban board [8] containing all blockers for 1.9.0.

[client] Zili Chen started a discussion on dropping the hardly used
*o.a.f.api.common.Program* interface to facilitate future changes in the
client code base. Users of o.a.f.api.common.Program please join the
discussion. [9]

[distributed coordination] Lamber-Ken asks for opinions about an ongoing
Jira ticket [10] in the context of the *leader selection*. He proposes that
the JobManager should not loose leadership if the connection to Zookeeper
is temporarily suspended, but only once the connection is lost. [11]

Notable Bugs
===========

Same as last week, very active Jira due to release testing, but only a few
bugs for released versions being filed.

[FLINK-13044] [1.8.1] A ticket I missed last week. Due to the way we
currently shade the com.amazonaws packages in flink-s3-fs-hadoop certain
configurations are not forwarded properly to the filesystem classes. The
Jira ticket contains a good explanation of the problem. [12]
