Resolution: Duplicate
> ContinuousFileMonitoringFunction wrongly ignores files with exact same

> Key: FLINK-8046
> URL: https://issues.apache.org/jira/browse/FLINK-8046
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 1.3.2
> Reporter: Juan Miguel Cejuela

> The current monitoring of files sets the internal variable
> `globalModificationTime` to filter out files that are "older". However, the
> current test (to check "older") does
> `boolean shouldIgnore = modificationTime <= globalModificationTime;` (rom
> `shouldIgnore`)
> The comparison should strictly be SMALLER (NOT smaller or equal). The method
> documentation also states "This happens if the modification time of the file
> is _smaller_ than...".
> The equality acceptance for "older", makes some files with same exact
> timestamp to be ignored. The behavior is also non-deterministic, as the first
> file to be accepted ("first" being pretty much random) makes the rest of
> files with same exact timestamp to be ignored.
