Dear community, happy to share this week's brief community digest with updates on Flink 1.8.3 and Flink 1.10, a discussion on how to facilitate easier Flink/Hive setups, a couple of blog posts and a bit more.
*Personal Note:* Thank you for reading these updates since I started them early this year. I will take a three week Christmas break and will be back with a Holiday season community update on the 12th of January. Flink Development ============== * [releases] Apache Flink 1.8.3 was released on Wednesday. [1,2] * [releases] The feature freeze for Apache Flink took place on Monday. The community is now working on testing, bug fixes and improving the documentation in order to create a first release candidate soon. [3] * [development process] Seth has revived the discussion on a past PR by Marta, which added a documentation style guide to the contributor guide. Please check it [4] out, if you are contributing documentation to Apache Flink. [5] * [security] Following a recent report to the Flink PMC of "exploiting" the Flink Web UI for remote code execution, Robert has started a discussion on how to improve the tooling/documentation to make users aware of this possibility and recommend securing this interface in production setups. [6] * [sql] Bowen has started a discussion on how to simplify the Flink-Hive setup for new users as currently users need to add some additional dependencies to the classpath manually. The discussion seems to conclude towards providing a single additional hive-uber jar, which contains all the required dependencies.
