---------------------------------
Summary: TailFile reading from NFS may introduce NUL characters.
Key: NIFI-7972
URL: https://issues.apache.org/jira/browse/NIFI-7972
Project: Apache NiFi
Issue Type: Improvement
Reporter: Tamas Palfy
On NFS - unlike on a normal file system - we can have a file where the first
chunk of bytes has not arrived yet but the second has - as some network packets
can arrive out of order. In this case we get the second chunk and the first
filled with NUL as a temporary value, until the real values arrive.
Solution: Add a boolean property by which the user can tell the processor to
yield (and try again later) whenever it encounters a NUL character. Requires
caution as a file that contains NUL characters on purpose would block the
processor indefinitely.
