solve:

1, it may be because the version of kafka and scala version is not the same, leading to find the relevant class

（1）查看kafka的版本
pwd
kafka_2.11-2.2.0       
kafak的安装目录上面自带的有版本，显示需要2.11的scala，kafka是2.2.0

（2）查看scala的版本
scala -version
Scala code runner version 2.11.12 -- Copyright 2002-2017, LAMP/EPFL
scala的版本是2.11.12

Method 2, if the version also supports may be missing jar package, can re-download a kafka

Official website: http://kafka.apache.org/downloads

3. The method may be repeated jar package, whether to add a check to the other jar inside ../kafka_2.11-2.2.0/libs

Join other hand jar jar may cause a conflict, the jar kafka not find the need, it can be removed.

For example, joined the KafkaOffsetMonitor-assembly-0.2.0.jar, will lead to more problems, remove it.

单机版
启动zookeeper:                
bin/zookeeper-server-start.sh config/zookeeper.properties > zookeeper-run.log 2>&1 &

启动kafka：
bin/kafka-server-start.sh config/server.properties > kafka-run.log 2>&1 &


要先创建 zookeeper-run.log和kafka-run.log 文件
