> When using the *{{Full Path}}* filter mode, the regex is applied to the URI returned
for each file which includes the scheme and authority (hostname, HA namespace, port).  For
the filter to work across multiple HDFS installations (such as a flow used on multiple environments
that is retrieved from NiFi Registry), the regex filter would have to account for the scheme
and authority by matching possible scheme and authority values.
> To make it easier for the user, the *{{Full Path}}* filter mode's filter regex should
only be applied to the path components of the URI, without the scheme and authority.  This
can be done by updating the filter for *{{Full Path}}* mode to use: [Path.getPathWithoutSchemeAndAuthority(Path)|].
 This will bring the regex values in line with the other modes, since those are only applied
to the value of *{{Path.getName()}}*.
> Migration guidance will be needed when this improvement is released.  Existing regex
values for *{{Full Path}}* filter mode that accepted any scheme and authority will still work.

>  Those that specify a scheme and authority will *_not_* work, and will have to be updated
to specify only path components.
