Description

The StandardProcessSession.exportTo(FlowFile, OutputStream) method does not increment the bytes read or bytes written properties after processing completes. Although the method uses a ByteCountingInputStream, the method does not use the accumulated bytes read.

As a result of this issue, Processors that use this exportTo() method do not show any information in the Bytes Read and Bytes Transferred sections of the Processor Status History.

This impacts InvokeHTTP and HandleHttpResponse among others.
