启动 kylin 时遇到如下报错(Hadoop3 环境下可能出现)：com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)V

报错信息如下：

解决方法：

复制Hadoop集群中的guava依赖包到$KYLIN_HOME/tool/ 和 $KYLIN_HOME/tomcat/lib/目录下，然后重启kylin bin/kylin.sh restart。

cp $HADOOP_HOME/share/hadoop/common/lib/guava-27.0-jre.jar $KYLIN_HOME/tool/

cp $HADOOP_HOME/share/hadoop/common/lib/guava-27.0-jre.jar $KYLIN_HOME/tomcat/lib/
