here moved snapshot jar in lib folder运行flume命令后出现此错误， 即
user @ ubuntu：〜/ hadoop_store / apache-flume-1.4.0-bin / bin $ ./flume-ng agent -n TwitterAgent -c conf -f ../ conf / twitter1.conf
也尝试了
user @ ubuntu：〜/ hadoop_store / apache-flume-1.4.0-bin / bin $ ./flume-ng agent -n TwitterAgent -c conf -f /home/user/hadoop_store/apache-flume-1.4。 0滨/ CONF / twitter1.conf
引起类似问题之一的原因是这样的， 这就是它的说法

答案 0 :(得分：0)
在flume / lib文件夹中添加flume-sources-1.0-SNAPSHOT.jar并将Twitter4j3.0.3.jar替换为可能有效的Twitter4j2.2.6.jar文件（核心，媒体和流文件）
