----------------------------------
Summary: JoltTransformRecord fails with various RecordReaders
Key: NIFI-6925
URL: https://issues.apache.org/jira/browse/NIFI-6925
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Matt Burgess
Assignee: Matt Burgess
When using JoltTransformRecord with readers such as AvroReader or CSVReader, an
error occurs when trying to transfer the original input flowfile to the
"original" relationship. The error indicates that it is reading from multiple
callbacks or that the input stream is still open. It happens to work with
JsonTreeReader because the underlying JSON parser closes the stream when no
more records are available.
This is a result of not explicitly closing the input stream before trying to
transfer the input flow file. It was not caught in the unit tests because
MockProcessSession doesn't keep track of the open reader count, so that should
be fixed as well. Fixing MockProcessSession will cause TestJoltTransformRecord
to fail before the fix for this case is applied.
