   With the default args to launch taskmanager pod, we can see the `libjemalloc` binary so is loaded in the memory process of task manager:

   When we add `disablejemalloc` in the launch args , we can see the `libjemalloc` binary so is not loaded in the memory process of task manager:

   BTW, to use `pmap` command in the pod, I installed the `procps` in the docker image which is not added in current PR.
