Description:
If FileSourceTextLinesITCase::testContinuousTextFileSource includes TM restarts
(after failing TM with TestingMiniCluster::terminateTaskExecutor, see
testContinuousTextFileSourceWithTaskManagerFailover in
[branch|https://github.com/azagrebin/flink/tree/FLINK-20118-it]) then sometimes
I observe duplicated lines in the output after running the whole test suite
FileSourceTextLinesITCase 5-10 times in IDE:
