--------------------------------
Summary: ReplaceText with Expression Language in Match Group
results in Data Loss/Corruption
Key: NIFI-8053
URL: https://issues.apache.org/jira/browse/NIFI-8053
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.12.1, 1.11.4
Environment: Running in Docker in Kubernetes on a Ubuntu Host
Reporter: Robin Lutz
Attachments: replace_text_race_condition.xml
This seems to be related to https://issues.apache.org/jira/browse/NIFI-7683
When I run a ReplaceText processor with multiple Threads and also manipulate
the result within an expression (im my case _${'$1':escapeJson()}_), the
processor will corrupt (cut off) or loose data.
I attached a template that demonstrates the case.
I did not see these problems in 1.11.2, never tried 1.11.3, and have i since
then with every release (1.12.0 and 1.12.1).
Finally, after noticing the bug mentioned above, I was able to reproduce the
problem.
Blocker and Important, because the user can loose data.
