I suspect the error is due to some file corruption that I may have caused
through some fault testing (hard reboot.)
My problem at this point is that it completely wedges the flow. I cannot not
examine or empty incoming connection and the processor is not discarding the
bad file. Any suggestions on how to get past this?
On the file corruption, are there any known issues with NiFi where file
corruption could occur when SIGKILLing NiFi? Not that, that is what I did, I
was doing a hard reboot, which could make the file system configuration
suspect, but if the problem is further up the stack I’d like to be aware of it.
Thanks,
Chris McDermott
