> 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
> Priority: Major
> 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.
