Событие прерывается в потоке

По умолчанию флюм считает одну строку одним событием, но я хочу сделать разбивку по каким-то другим критериям, как этого можно добиться в флюме?

это файл журнала, который я пишу в HBase. Линия, выделенная жирным шрифтом, я хочу как одно событие, а остальное как другое событие. В основном я хочу разбить события на дату? Можно ли сделать в флюме?

Спасибо и с уважением Чхая
