--------------------------------
Summary: Provenance Repository will sometimes spew error messages
about ZLIB End-of-File messages on restart
Key: NIFI-1076
URL: https://issues.apache.org/jira/browse/NIFI-1076
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Mark Payne
Priority: Minor
We see the following error message sometimes on restart of NiFi. This seems to
be due to the fact that the file was created but had no data written to it.
This shouldn't really hurt anything, as there is no data in the file. The file
could simply be ignored. It is probably best to change the ERROR message to a
WARN or even an INFO message, though, and indicate that the file had no data
and so is being skipped.
