------------------------------------
Summary: TailFile not ingesting data when tailed file is moved
with no rolling pattern
Key: NIFI-1959
URL: https://issues.apache.org/jira/browse/NIFI-1959
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 0.6.1
Reporter: Pierre Villard
Assignee: Pierre Villard
Priority: Minor
In case "Rolling Filename Pattern" is not set by user and if the tailed file is
moved, then the new file will not be tailed.
Besides, in such case, the processor will be endlessly triggered without
ingesting data: it creates a lot of tasks and consumes CPU. The reason is it
never goes in if statement L448.
A solution is to look at size() and lastUpdated() of the tailed file to detect
a "rollover". However it won't allow the processor to ingest the potential data
added in the tailed file just before being moved.
