Jiayi Liao commented on FLINK-14364:
------------------------------------
[~twalthr]
I've checked jackson codes and find out that this allowComments only work with
multiple lines message by using objectReader.readValues(message) insteand of
objectReader.readValue(message). I'm not sure if this is a jackson bug or
expected behaviour. But either way I think we should add this into
#CsvValidator#validate.
> Allow comments fail when not ignore parse errors in
> CsvRowDeserializationSchema
