@Logann    NiFi does not offer local user creation for authentication.  There is no way to create local users and assign them passwords for the purpose of user authentication. User Authentication require either: 1. User certificates (always requested by NiFi during TLS handshake) 2. Spnego auth (Spnego auth challenge sent to browser if spnego properties configured in nifi.properties.  This request is only sent if 1 did not result in client certificate in response from client) 3. Configured login provider (uses login-provider configured in login-identity-providers.xml and referenced in nifi.properties file.  Only used if both 1 and 2 did not provide client/user authentication already). 4. NiFi will also support other OpenID Connect supported authentication providers. Hope this helps, Matt ... View more

@memad    If your GetFile processor is consuming files before they have finished writing there are a few changes that may help: 1. How are files being written in to the directory?  The default "File Filter" will ignore files that start with a ".".  If it is possible to change how files are being written to the directory, that will solve your issue through a file filter.  For example.... writing new files to directory as ".<filename>" and upon successful write does a rename to remove the dot (this is how ssh works).  But you can of course setup any file filter that works for you, 2. Assuming the process that is writing files to the directory is always updating the timestamp on the file, you can use the "Minimum File Age" property to prevent the GetFile from consuming a file until the last modified timestamp in the file has not updated for the configured amount of time.  This works in most cases, except when there may be long pauses in the write process that exceeds the configured Min File Age time. Hope this helps, Matt ... View more
