问题描述
我正在尝试在 AWS 实例上设置 kafka-connect-cassandra.
I am trying to setup kafka-connect-cassandra on an AWS instance.
我在 connect-avro-distributed.properties 文件中设置了 plugin.path:
I have setup plugin.path in connect-avro-distributed.properties file:
plugin.path=/home/ubuntu/kafka_2.11-1.0.0/plugins
我有 kafka-connect-cassandra-1.0.0-1.0.0-all.jar 在:
/home/ubuntu/kafka_2.11-1.0.0/plugins/lib
这是回溯:

The first entry in jvm.classpath is the location where I have kafka-connect-cassandra.jar, inside plugin/lib.
guava.jars:
这些是番石榴罐的路径.我应该将 kafka-connect-cassandra.jar 放在哪里，还是应该删除这些 jar 中的任何一个?
These are the paths of guava jars. Where should I place the kafka-connect-cassandra.jar or should I just remove any of these jars?

/home/ubuntu/cassandra/apache-cassandra-3.11.1/lib/guava-18.0.jar
请帮助我.
推荐答案
Connect 框架当前带有 guava-20.0.jar 以便使用 Reflections 并能够扫描您的 插件.连接插件的路径.
The Connect framework currently carries guava-20.0.jar in order to use Reflections and be able to scan your plugin.path for Connect plugins.
如果您使用以下 bin 脚本之一启动 Connect，则 Connect 框架的依赖项会添加到您的 CLASSPATH:connect-distributed 或 connect-standalone.
Connect framework's dependencies are added to your CLASSPATH if you are starting Connect using one of its bin scripts: connect-distributed or connect-standalone.
但是，不知何故，旧版本的番石榴首先驻留在您的 CLASSPATH 中(可能是因为您已将 CLASSPATH 设置为包含此类依赖项)，然后 Connect 无法扫描您的 plugin.path 带有番石榴版本 <20.这就是你的异常所表明的.该 Connect 无法使用它在您的 CLASSPATH 中找到的番石榴版本扫描 plugin.path.
However, somehow an older version of guava is residing first in your CLASSPATH (maybe because you've set the CLASSPATH to include such a dependency), and then Connect is unable to scan your plugin.path with a guava version < 20. That's what your exception indicates. That Connect can't scan the plugin.path with the version of guava it finds in your CLASSPATH.
您的 plugin.path 应该包含您的插件，每个插件都在自己的目录中.例如，类似于上面的内容:
Your plugin.path should contain your plugins, each on its own directory. For example, similarly to what you have above:
plugin.path=/home/ubuntu/connect 与
/home/ubuntu/connect/kafka_2.11-1.0.0/ 和
/home/ubuntu/connect/kafka-connect-cassandra-1.0.0-1.0.0-all.jar
根据您的示例，上面的布局用于表明插件不应包含其他插件，但不建议将您的 plugin.path 设置为用户的主目录.
The layout above is used to make the point that plugins should not contain other plugins according to your example, but it's not recommended to set your plugin.path to a user's home directory.
