For an hierarchal workflow of the following structure
uber-dax

lets say we want uber-dax and dax-group wf's to be executed in shared filesystem setup , and dax.0 , dax.1 to be executed in the condorio mode

The dax.1 when planned by pegasus will see pegasus.execute.*.filesystem.local set to false , as that is inherited from dax-group

Because of this , when planner on encountered the pegasus.data.configuration property as condorio tries to pegasus.execute.*.filesystem.local to true , it does not saying it has been already set in properties

012.06.22 17:09:16.941 EDT: [WARNING] Property Key pegasus.execute.*.filesystem.local already set to false. Will not be set to - true

The current logic says that
If this is already set in the properties, don't override

One way to get around this is to have pegasus.execute.*.filesystem.local set explicitly in the DAX

<dax id='scan-flowgid0' file='scan-flow.0.dax' >
<argument>-Dpegasus.execute.*.filesystem.local=true -Dpegasus.data.configuration=condorio --staging-site=local --verbose --verbose --verbose --force --sites condorpool</argument>
</dax>
