解决办法：
在 ~/.bashrc文件里面添加如下的信息
export HIVE_CONF_DIR=/data1/hadoop/hive/conf
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/*
重新source一下
# source ~/.bashrc
接着执行，报如下错误

这个是由于hive3.x里面使用的disruptor版本是3.3.6，可能是版本过低导致没有对应的方法
解决：
下载高版本的disruptor包，下载地址：
https://www.mvnjar.com/com.lmax/disruptor/3.3.11/detail.html
当前下载的版本是3.3.11
把disruptor对应的jar包放到sqoop的lib目录下
重新执行创建表就可以了
hive查看创建的表
默认创建在default数据库
0: jdbc:hive2://localhost:10000> show create table mysqltoa;
