-------------------------------------
Hi [~vmaddela],
I hope I understand your need correctly.
I assume you mentioned DynamicProperties because you wanted to avoid setting a
static exact configuration for FetchSFTP, instead you wanted a FetchSFTP
instance to handle different SFTP servers and file paths. NiFi Expression
Language can be used to realize these dynamic behavior.
I summarized how to use ListSFTP and FetchSFTP with NiFi Expression Language to
fetch contents from SFTP servers by FetchSFTP dynamically in this [Gist
page|https://gist.github.com/ijokarumawak/bf5705b70a75779d763f20cdb27d4162].
Lastly, please send a question to [NiFi Users Mailing
List|https://nifi.apache.org/mailing_lists.html] to ask how to do certain
things, before submitting a JIRA.
I'm now closing this JIRA, but please feel free to re-open it if something
needs to be improved in NiFi. Thanks!

> Hi All,
> We are looking to have dynamic behavior for FTP/SFTP processors.
> 1) GETFTP processor should be used only as starting point in a flow (Not
> supported to use it in middle of the flow)
> 2) FetchFTP: This supports using in middle of the flow, but doesnot
> support to pass Dynamic properties
> When we look into code we identified reasons for not supporting
> In
> GetFTP/GetSFTP:
> @InputRequirement(Requirement.INPUT_FORBIDDEN) instead of
> @InputRequirement(Requirement.INPUT_REQUIRED)
> FetchFTP/FetchSFTO:
> Doesn’t contain @DynamicProperties() in the code
> Can you please some help someone how can we build the code and deploy by our
> self. Appreciate a link or tutorial for building code after modification
