Yun Tang commented on FLINK-34976:
----------------------------------
I don't think the running Flink process would drop the {{LD_PRELOAD}}
environment, please use `pmap` to check whether {{jemalloc.so}} is used by your
process.
> LD_PRELOAD environment may not be effective after su to flink user

> Components: flink-docker
> Affects Versions: 1.19.0
> Reporter: xiaogang zhou
> Priority: Major

> I am not sure if LD_PRELOAD still takes effect after drop_privs_cmd. Should
> we create a .bashrc file in home directory of flink, and export LD_PRELOAD
> for flink user？
