-----------------------------------
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).
