目前有两种 Kafka Connect 正在收集日志。 connect-rest.log.2018-07-01-21 , connect-rest.log.2018-07-01-22 ... connectDistributed.out 问题是我不知道如何配置 connectDistributed.out Kafka连接文件。以下是文件的示例输出：

[2018-07-11 08:42:40,798] INFO WorkerSinkTask{id=elasticsearch-sink- 
connector-0} Committing offsets asynchronously using sequence number 
216: {test-1=OffsetAndMetadata{offset=476028, metadata=‘’}, 
test-0=OffsetAndMetadata{offset=478923, metadata=‘’}, 
test-2=OffsetAndMetadata{offset=477944, metadata=‘’}} 
(org.apache.kafka.connect.runtime.WorkerSinkTask:325)
[2018-07-11 08:43:40,798] INFO WorkerSinkTask{id=elasticsearch-sink-connector0} 
Committing offsets asynchronously using sequence number 217: 
{test-1=OffsetAndMetadata{offset=476404, metadata=‘’}, 
test-0=OffsetAndMetadata{offset=479241, metadata=‘’}, 
test-2=OffsetAndMetadata{offset=478316, metadata=‘’}} 
(org.apache.kafka.connect.runtime.WorkerSinkTask:325)

由于没有配置任何日志选项，文件大小会随着时间的推移而变大。今天，它达到20gb，我不得不手动清空文件。所以我的问题是如何配置它 connectDistributed.out ? 我正在为其他组件（如kafka代理日志）配置日志选项。
下面是下与kafka connect相关的一些日志配置 confluent-4.1.0/etc/kafka 我正在用的。
