@chenyangxueHDU Why do u need this in initcontainer?

before the job container running, i will mkdir on the glusterfs in the initContainers, and only one pod will do this.

There is no difference for you to mkdir in initcontainer or in normal container, assume you have 2 pods per task, each pod share the same pod template. In other word, you will have 2 init containers too.
