[HTCondor-users] JobWrapper fails to execute after upgrade to 8.8.11

["Fischer, Max (SCC)" <max.fischer@xxxxxxx>]

Hi all,

weâre currently preparing to upgrade our Batch Cluster from HTCondor 8.6 to 8.8. However, our test node shows an issue that I do not understand.

We use a `USER_JOB_WRAPPER` to run all jobs in a login-shell environment. The script is basically this:

	#!/bin/bash -l
	exec "$@â

Since the upgrade to 8.8.11, condor fails to execute the job-wrapper with `child exec failed due to bad interpreter (/bin/bash)` [0]. Obviously, the machine does have `/bin/bash` and executing the wrapper as either root or condor works fine.
No changes were made other than upgrading HTCondor and restarting it.

Is there any change that could affect this? Do we have to be aware of how HTCondor determines the PATH?
Iâve only found Ticket #6904, but it seems unrelated.

Cheers,
Max
