             Summary: NoSuchMethodError happened when run flume agent using kudu flume sink
                 Key: KUDU-2241
                 URL: https://issues.apache.org/jira/browse/KUDU-2241
             Project: Kudu
          Issue Type: Bug
          Components: flume-sink
    Affects Versions: 1.5.0
            Reporter: Changyao Ye


I've installed kudu and flume components from cloudera manager, and when I start flume agent the following error happened.
```
17/12/11 10:46:29 ERROR node.PollingPropertiesFileConfigurationProvider: Unhandled error

Version infomation:
- flume: 1.6.0-cdh5.13.0
- kudu: 1.5.0-cdh5.13.0

I checked the classpath of flume agent and found that maybe there is version conflict of guava jar between flume and kudu flume sink(kudu-flume-sink-1.5.0-cdh5.13.0.jar) which includes shaded guava jar.

Maybe this problem related to the changes made [here|https://github.com/apache/kudu/commit/5a258508f8d560f630512c237711a65cd137c6b3].

To make flume agent run properly, I excluded related class(ImmutableMap etc) from shaded settings in pom.xml and found that worked.
