Thanks to Quanlong for the work on this, it's very valuable for those who can't upgrade their Hive.
We backported the following patches to our internal Impala 3.4.0 cluster and they have been running well in production. These patches are small and don't seem to be in the 3.4.2 git log right now, so I suggest considering including these fixes in the upcoming 3.4.2 release: - IMPALA-12565: Fix crash triggered by calling pmod() UDF. - IMPALA-10310: Fix inability to skip rows in a parquet file on NextRowGroup. - IMPALA-9952: Fix page index filtering for empty pages. - IMPALA-10257: Relax check for page filtering. - IMPALA-5476: Fix issue where a catalogd restart results in stale metadata.

Quanlong Huang <hu...@gmail.com> 于2024年1月27日周六 06:59写道： Hi all, We still have users on the 3.x branch since they can't upgrade their Hive to newer versions. It's reported that the 3.4.1 release is not compilable now (IMPALA-12755). It'd be nice to have a buildable release for 3.4. I propose doing a maintenance release of 3.4.2 to fix the build issue and I volunteer to manage the release of it. It can branch out based on the HEAD of 3.4.1. We can also add some fixes (some are already in 3.x): - IMPALA-11296: Fix infinite loop when reading orc files - IMPALA-11444: Fix wrong results when reading wide rows from ORC - IMPALA-12102: Avoid memory leaks in the handling of JNI exceptions - IMPALA-11406: Fix incorrect duration log for authorization Optional items: - Backport RPM/DEB packaging support (IMPALA-10262) so it's easier to distribute Impala. - Backport script changes to support building on Ubuntu 18.04 and 20.04 (IMPALA-10007). I tried a branch like this: https://github.com/stiga-huang/impala/commits/branch-3.4.2 It passed the CORE tests: https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/19973/ Please speak up and let the community know your ideas, especially any bug fixes that you want to backport to 3.4.2. All feedback is welcome! PS This is not a VOTE thread but only a DISCUSS thread. Thanks, Quanlong
