-----------------------------------
Summary: Base64EncodeContext processor causing content repository
to grow in size
Key: NIFI-7058
URL: https://issues.apache.org/jira/browse/NIFI-7058
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.10.0
Environment: NiFi Single Node, NiFi Cluster
Reporter: Stefano Piana
Attachments: Base64EncodeContent_bug.xml
We encountered this bug causing NiFi content repository to grow in size (and
not getting cleaned up properly until a restart) when passing flowfiles with
empty content to the Base64EncodeContext processor. This happens in particular
when flowfiles with any content are cleaned (i.e., with a ReplaceText
processor) then passed with the empty content to the Base64EncodeContent both
in decode or encode modality. We observed this behaviour on NiFi 1.10 both on
windows and Ubuntu 18.04, java 8 and 11. Here attached a simple template of a
flow to reproduce the bug,
it should generate a few gigabytes of corrupted content repository if run for a
couple of minutes.
