Hi team, I just created a 4.0.1 branch to address issues we should fix on Impala 4.0.0. For instance, Impala-4.0.0 is built on a snapshot version of Kudu which can't be deployed on any kudu released versions (IMPALA-10859). Here are jiras targets on 4.0.1: https://issues.apache.org/jira/browse/IMPALA-10828?jql=project%3D%22IMPALA%22%20AND%20%22Target%20Version%22%3D%22Impala%204.0.1%22%20ORDER%20BY%20priority%20ASC
I also backport some bug fixes which don't have merge conflicts. Please let me know if you think a fix is critical and should also be backported. Tests: Core tests with DEBUG build: https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/14843/ Exhaustive tests with RELEASE build: https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/14844/ Thanks, Quanlong
