Rohini Palaniswamy commented on OOZIE-3068:
-------------------------------------------

Another reason , is used as separator is that the path and file separators vary between Windows and Linux. So in general , is used in configuration and during the actual env variable construction appropriate separator is chosen.

> It will be confusing for users to deal with different conventions.
