[ANNOUNCE] Weekly Community Update 2020/04

[Konstantin Knauf-3]

Dear community,

happy to share a brief community digest after a rather quite week including
updates on Flink 1.9.2 and Flink 1.10, and the ongoing votes on FLIP-27
(New Source Interface) and FLIP-92 (N-Ary Stream Operator).

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

* [releases] Hequn has published the first release candidate for Apache
Flink 1.9.2 and is waiting for votes and feedback. [1]

* [releases] No feedback on the RC0 for Flink 1.10 so far. Still, I assume
a first release (non-preview) candidate for Flink 1.10 is just around the
corner as only a few blockers remain on the board for 1.10. [2]

* [runtime] Piotr has started a vote on adding an N-Ary Stream Operator
(FLIP-92). [3]

* [connectors] Becket has resumed the vote on highly anticipated FLIP-27,
the new source interface. [4]

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

[FLINK-15575] [1.9.1] Incomplete shading/relocation of some dependencies of
the Azure filesystem can result in classloading conflicts. This only
applies to users using Application Clusters (Job Clusters) prior to Flink
1.10 as these do not use a dedicated classloader for user code. Resolved in
1.9.2 and 1.10. [5]

[FLINK-13758] [1.8.3] [1.9.1] As a user you can use Flink's distributed
cache to make files available to all user defined functions running in the
cluster. This did not work for files stored in HDFS for a while. Resolved
in 1.8.4, 1.9.2 and 1.10. [6]
