Joe Witt created NIFI-12996:
-------------------------------
Summary: CompressContent Zstd compression and decompression
appears broken with missing classes
Key: NIFI-12996
URL: https://issues.apache.org/jira/browse/NIFI-12996
Project: Apache NiFi
Issue Type: Improvement
Affects Versions: 2.0.0-M2, 1.25.0
Reporter: Joe Witt
Assignee: Joe Witt
In Apache Slack a user reported this was broken for them in NiFi 1.25.0 but
used to work in 1.19.1.
On apache 2.0 m2+latest I can reproduce this by simply trying to use it at all.
First question is do we not have unit tests but anyway this needs to be
evaluated as to why it isn't working.
