Hi All, With the automatic commit flow to the 2.x branch being disabled, I'd like to suggest that we deprecate support for some older operating systems on the 3.x branch. This would allow us to get rid of almost all the checks in common/config.h.in as well as some workarounds in the code. It would also simplify the upcoming rebase of the KRPC code (IMPALA-7006).
I'd like to propose that we pick Ubuntu 14.04, CentOS 6.8, and SLES 12 as the minimum operating system versions on which Impala has to compile and pass all tests. I'd also like to deprecate support for Java 7 and require Java 8 for all changes going forward. To my knowledge these are the minimum versions that people use for development and deployment of the 3.x branch. I'm curious what others think. Cheers, Lars
