Change subject: IMPALA-14509: Let Ozone set OZONE_OPTS
......................................................................
Patch Set 1: Code-Review+2
Confirmed that ozone-1.4.0.7.3.1.500-30/libexec/ozone-functions.sh has this
function:
## @description Adds default GC parameters
## @description Only for server components and only if no other -XX parameters
## @description are set
## @audience private
## @stability evolving
## @replaceable yes
function ozone_add_default_gc_opts
{
java_major_version=$(ozone_get_java_major_version)
if [[ "${OZONE_SUBCMD_SUPPORTDAEMONIZATION}" == true ]]; then
if [[ ! "$OZONE_OPTS" =~ "-XX" ]] ; then
OZONE_OPTS="${OZONE_OPTS} -XX:ParallelGCThreads=8"
if [[ "$java_major_version" -lt 15 ]]; then
OZONE_OPTS="${OZONE_OPTS} -XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled"
ozone_error "No '-XX:...' jvm parameters are set. Adding safer GC
settings '-XX:ParallelGCThreads=8 -XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled' to the
OZONE_OPTS"
else
ozone_error "No '-XX:...' jvm parameters are set. Adding safer GC
settings '-XX:ParallelGCThreads=8' to the OZONE_OPTS"
