[jira] [Created] (NIFI-7304) Default value for content length filter blocks Site to Site communication

Andy LoPresto created NIFI-7304:
-----------------------------------

             Summary: Default value for content length filter blocks Site to Site communication
                 Key: NIFI-7304
                 URL: https://issues.apache.org/jira/browse/NIFI-7304
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.12.0
            Reporter: Andy LoPresto
            Assignee: Andy LoPresto


When the content-length filter was introduced in NIFI-7153, it did not separate Site to Site (S2S) or cluster request replication requests from user-generated requests. With the default value of 20 MB, it is very likely that legitimate requests of this nature will be unexpectedly blocked. 

The immediate fix is to change the default value in {{nifi.properties}} to empty and only enable this functionality when a value is provided. 

A subtask will be opened to investigate if these requests should be excluded from the length limiting filter (either by convention or via an admin-enumerated exclusion list/setting).
