> Key: NIFI-3055
> URL: https://issues.apache.org/jira/browse/NIFI-3055
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.0.0, 0.7.1
> Reporter: Brandon DeVries
> Assignee: Joe Skora
> Priority: Blocker
> Fix For: 0.8.0, 1.2.0
>
>
> StandardRecordWriter.writeRecord()\[1] uses DataOutputStream.writeUTF()\[2]
> without checking the length of the value to be written. If this length is
> greater than 65535 (2^16 - 1), you get a UTFDataFormatException "encoded
> string too long..."\[3]. Ultimately, this can result in an
> IllegalStateException\[4], -bringing a halt to the data flow- causing
> PersistentProvenanceRepository "Unable to merge <prov_journal> with other
> Journal Files due to..." WARNings.
> Several of the field values being written in this way are pre-defined, and
> thus not likely an issue. However, the "details" field can be populated by a
> processor, and can be of an arbitrary length. -Additionally, if the detail
> filed is indexed (which I didn't investigate, but I'm sure is easy enough to
> determine), then the length might be subject to the Lucene limit discussed in
> NIFI-2787-.
