Hi Hadoop devs, Last week, there was a Hadoop build failure on Debian 10 caused by https://github.com/apache/hadoop/pull/3988. In dev-support/jenkins.sh, there's the capability to build and test Hadoop across the supported platforms. Currently, we're limiting this only for those PRs having only C/C++ changes[1], since C/C++ changes are more likely to cause cross-platform build issues and bypassing the full platform build for non C/C++ PRs would save a great deal of CI time. However, the build failure caused by PR #3988 motivates me to enable the capability to build and test Hadoop for all the supported platforms for ALL the PRs.
While this may cause longer CI run duration for each PR, it would immensely minimize the risk of breaking Hadoop across platforms and saves us a lot of debugging time. Kindly post your opinion regarding this and I'll move to enable this capability for all PRs if the response is sufficiently positive.
