-------------------------------------
Summary: StandardRecordWriter can throw UTFDataFormatException
Key: NIFI-3055
URL: https://issues.apache.org/jira/browse/NIFI-3055
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.7.1, 1.0.0
Reporter: Brandon DeVries
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]. 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.
