At work, in my configuration, the master only do balancing stuff. The master as no executor, but many slaves do the builds.

When the plugin do a scm-polling, if no executor was set to the master (0 executor) the plugin does not append path to cleartool command. In my configuration, it fail because cleartool is not in the PATH. (i have not the rights to define env variable in the system)

If i set an executor on the master, the path set in the clearcase installation field is taken. (even if the job is forced to run on a slave)

Even if i try to manualy set clearcase path on slaves, in clearcase installation field, or in PATH variable, it does not work.

Here the trace when an executor is setted :
