flume报错：ERROR [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.flume.sink.hdfs.HDFSEventS

flume传输文件到hdfs时报错：

ERROR [SinkRunner-PollingRunner-DefaultSinkProcessor] (org.apache.flume.sink.hdfs.HDFSEventSink.process:459)  - process failed

解决方法：
com.google.common.base.Preconditions.checkArgument 这是因为flume内依赖的guava.jar和hadoop内的版本不一致造成的。
检验方法：
查看hadoop安装目录下share/hadoop/common/lib内guava.jar版本
查看flume安装目录下lib内guava.jar的版本
如果两者不一致，删除版本低的，并拷贝高版本过去
