我下载了Confluent5.4.2版本和Sink2连接器（5.4.2）。我使用的是mapr版本的6.1.0，jar包含在类路径中。我注意到kafka connect hdfs有hadoop版本2.7.3，但我得到一个错误：

[2021-04-26 16:23:29,091] ERROR Stopping due to error (org.apache.kafka.connect.cli.ConnectDistributed:84)
java.lang.IncompatibleClassChangeError: Implementing class

这是因为hadoop版本冲突吗？如果是，我怎么知道是哪一个？以下是kafka connect hdfs包中包含的hadoop jar：
