Allen Wittenauer commented on HADOOP-11984:
-------------------------------------------
1. Minor nit:
{code}
(default defined in Hadoop build)
{code}
s,Hadoop,${PROJECT_NAME},g
2. I'm confused as to what the intent here is:
{code}
+ echo "--test-threads=<int> Number of tests to run in parallel (default
defined in Hadoop build)"
{code}
OK, --test-threads takes an int.
{code}
+ --test-threads=*)
+ TEST_THREADS=${i#*=}
+ ;;
{code}
Mhmm ok.
{code}
+ if [[ ${TEST_PARALLEL} == "true" ]] ; then
+ PARALLEL_TESTS_PROFILE=-Pparallel-tests
+ if [[ -z ${TEST_THREADS:-} ]]; then
+ TESTS_THREAD_COUNT=$TEST_THREADS
+ fi
+ fi
{code}
OK, so we've got a count var we're probably going to finish setting up later.
{code}
+ echo_and_redirect "${test_logfile}" "${MVN}" "${MAVEN_ARGS[@]}" clean
install -fae ${NATIVE_PROFILE} ${REQUIRE_TEST_LIB_HADOOP}
${PARALLEL_TESTS_PROFILE} ${TESTS_THREAD_COUNT}
{code}
... umm, the number is now naked on the maven command line.
If I had to guess, you intended for TESTS_THREAD_COUNT="-Dblah=TEST_COUNT"
rather than be a number down here on the maven command line.

> for running JUnit tests in multiple concurrent processes. This issue
> proposes to activate that profile during pre-commit to speed up execution.
