> 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)|https://hadoop.apache.org/docs/r3.0.0/api/org/apache/hadoop/fs/Path.html#getPathWithoutSchemeAndAuthority-org.apache.hadoop.fs.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.
