----------------------------------
Since Flink supports arm image from flink-1.14, [~nferrario] could you also
create PR targets for {{dev-1.14}} and {{dev-1.15}} branch? Remember to modify
your commit message with the ticket ID {{{}[FLINK-xxx]{}}}.
> 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
> fi
> }
