方案一：手动拷贝需要的相关jar包

flume对接HBASE报错，找不到相关的类：

报错hbase相关日志：

18 五月 2021 17:25:50,633 ERROR [lifecycleSupervisor-1-2] (org.apache.flume.lifecycle.LifecycleSupervisor$MonitorRunnable.run:251)  - Unable to start SinkRunner: { policy:org.apache.flume.sink.DefaultSinkProcessor@4b591129 counterGroup:{ name:null counters:{} } } - Exception follows.
java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/protobuf/generated/MasterProtos$MasterService$BlockingInterface

则需要将hbase lib下的相关包拷贝到flume lib目录下：

scp hbase*.jar xxx.xx.x.xx:/home/root/programs/flume/lib/ 
scp metrics*.jar xxx.xx.x.xx:/home/root/programs/flume/lib/ 
scp netty*.jar xxx.xx.x.xx:/home/root/programs/flume/lib/ 
scp protobuf*.jar xxx.xx.x.xx:/home/root/programs/flume/lib/

报错zk相关日志：

则需要把zk相关jar（zookeeper-3.4.6.jar、zookeeper-jute-3.5.8.jar）包拷贝到flume lib下；

方案二：

配置相关服务的环境变量

ps：本质这种框架一般都是指定入口类，调动相关jar包进行程序服务，缺少哪些类报错日志一般会详细指明，还是要仔细观察相关报错日志内容
