Subject Fetch file - false file not founds
Date Thu, 20 Oct 2016 20:55:19 GMT
I think I have found a bug in FetchFile.

I have a flow that reads files from an NFS volume.  To simulate the NFS server being offline/unreachable
I am using IP tables to block all TCP traffic between the NFS server and the host running

Trying to read files using FetchFile, I am seeing

2016-10-20 20:34:31,789 ERROR [Timer-Driven Process Thread-4] o.a.nifi.processors.standard.FetchFile

not exist; routing to not.found

The file is actually there, but of course it is inaccessible because the network traffic is

I see the code is using File.exists().

This bug<> report suggest that it should
instead use


Should I file a JIRA?
