Kafka Connect - 文件源连接器错误

Question

我正在玩 Conluent Platform/Kafka Connect 和类似的东西，我想运行几个例子。

我从 here 开始关注快速入门。意思是：

安装 Confluent Platform (v3.2.1)
运行 Zookeeper、Kafka Broker 和 Schema Register
运行读取文件数据的例子（witk Kafka Connect）

我运行这个命令（3号）：

[root@sandbox confluent-3.2.1]# ./bin/connect-standalone ./etc/schema-registry/connect-avro-standalone.properties ./etc/kafka/connect-file-source.properties

但得到了这个结果：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/root/confluent-3.2.1/etc/kafka-connect-opentsdb/target/scala-2.11/kafka-connect-opentsdb-assembly-0.0.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]

Exception in thread "main" java.lang.NoSuchFieldError: SYSTEM
    at org.apache.kafka.connect.cli.ConnectStandalone.main(ConnectStandalone.java:67)

在ConnectStandalone.java文件的第67行是这样的：Time time = Time.SYSTEM;，但我不知道，为什么它会导致任何错误。有任何想法吗？我错过了什么重要的东西吗？

我的工作环境：

Hortonworks 沙盒 [HDP 2.5.0.0-1245]
CentOS 6.8 版
Java: openjdk 版本“1.8.0_121”

Answer 1

我在"ConnectStandalone.java file on the line 67 is this: Time time = Time.SYSTEM"

遇到了同样的问题

可能 OpenTSDB 连接器 取决于 kafka-clients-versionA.jar 的版本与 kafka-clients-versionB.jar 下./libs.
