Nicolas Ferrario commented on FLINK-28057:
------------------------------------------
[~chesnay] this happens because the CI host doesn’t have jemalloc installed,
and it’s actually running as “bare metal”. We’d need to change the test suite
to execute the Docker image instead to make that warning go away.
> LD_PRELOAD is hardcoded to x64 on flink-docker

> ARM images are not using jemalloc because LD_PRELOAD is hardcoded to use an
> x64 path, causing this error:
> {noformat}
> ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libjemalloc.so' from
> LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
> {noformat}
> Right now docker-entrypoint is using this:
> {code:sh}
> maybe_enable_jemalloc() {
> if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
> export LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
> fi
> }
> {code}
> I propose we use this instead:
> {code:sh}
> maybe_enable_jemalloc() {
> if [ "${DISABLE_JEMALLOC:-false}" == "false" ]; then
> # Maybe use export LD_PRELOAD=$LD_PRELOAD:/usr/lib/$(uname
> -i)-linux-gnu/libjemalloc.so
> if [[ `uname -i` == 'aarch64' ]]; then
> export
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/aarch64-linux-gnu/libjemalloc.so
> else
> export
> LD_PRELOAD=$LD_PRELOAD:/usr/lib/x86_64-linux-gnu/libjemalloc.so
> fi
