You shouldn't have to, but there may be a bug in the system. Try manually setting both envars and see if it fixes the problem.

But I see that openmpi-sessions* directory is still getting created under /tmp. How do I overcome this problem so that openmpi-sessions* directory also gets created under the same directory I have defined for “opal_cr_tmp_dir”?
