我在其中一个AWS环境中使用了Ambari服务。已经有一个与Zookeeper和HBase数据库一起运行的Kafka消息队列。我使用了Landoop HBaseSink连接器。 https://docs.lenses.io/connectors/sink/hbase.html
我能够使用Avro Schema Registry读写Kafka。连接器已经在主题中检测到新消息。但是，在将数据写入HBase时存在问题。它给了我一个Nullpointerexception，它似乎与Zookeeper有关。
我已经尝试找出连接器如何检测到hbase集群，并且似乎它是通过zookeeper自动完成的。在上面提供的网站上，我说我应该编辑hbase-site.xml并将其添加到连接器属性中的path.plugin中。
这些是我的连接器属性。

连接器的错误消息如下：

编辑： 我正在这样启动连接器（具有上述属性文件）：
./bin/connect-standalone.sh ./config/connect-standalone.properties ./config/connect-hbase-sink.properties
