Thanks @kerneltime for working on this.

Filtering checks based on paths is performed by dev-support/ci/selective_ci_checks.sh. Please add it to the pattern here:

ozone/dev-support/ci/selective_ci_checks.sh

Lines 233 to 237 in c1efa33

	local ignore_array=(
	"^hadoop-ozone/dist/src/main/k8s"
	"^hadoop-ozone/dist/src/main/license"
	"\.md$"
	)

and here:

ozone/dev-support/ci/selective_ci_checks.sh

Lines 481 to 497 in c1efa33

	# Counts other files which do not need to trigger any functional test
	# (i.e. no compose/integration/kubernetes)
	function get_count_misc_files() {
	start_end::group_start "Count misc. files"
	local pattern_array=(
	"^dev-support/ci/pr_title_check"
	"^.github"
	"^hadoop-hdds/dev-support/checkstyle"
	"^hadoop-ozone/dev-support/checks"
	"^hadoop-ozone/dev-support/intellij"
	"^hadoop-ozone/dist/src/main/license"
	"\.bats$"
	"\.txt$"
	"\.md$"
	"findbugsExcludeFile.xml"
	"/NOTICE$"
	)

We also have a unit test for this script. Please add a test case similar to the following, using the hash of a commit that only changed dashboard files (e.g. 039dea9):

ozone/dev-support/ci/selective_ci_checks.bats

Lines 400 to 410 in c1efa33

	@test "IntelliJ config" {
	run dev-support/ci/selective_ci_checks.sh 92bf0913b6
	assert_output -p 'basic-checks=["rat"]'
	assert_output -p needs-build=false
	assert_output -p needs-compile=false
	assert_output -p needs-compose-tests=false
	assert_output -p needs-dependency-check=false
	assert_output -p needs-integration-tests=false
	assert_output -p needs-kubernetes-tests=false
	}

You can then test it locally by running:

hadoop-ozone/dev-support/checks/bats.sh
