用户行为分析传送门
我的版本
ubantu16
hadoop 3.1.3
habse 2.2.2
hive3.1.3
zookeeper3.8.3
sqoop 1.46/1.47 我sqoop把MySQL数据往hbase导数据时候有问题

密码相关的问题
第一个是root账户的密码，ubantu是没给root设置密码的，那怎么且换root用户呢
sudo -i #此时就已经切换到root用户了passwd root #设置root账户密码第二个问题是MySQL root的密码
sudo mysql #进入MySQL#登录进去之后use mysql;ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';flush privileges;ubuntu22.04 密钥存储在过时的 trusted.gpg 密钥环中
遇到缺密钥的情况：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys这里换成缺的那个密钥我的配置：

问题1
FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
问题2
hive插入数据报错
问题3
原因：
把hive/lib下的guava-19.0.jar 删掉将hadoop\share\hadoop\common\lib 下的包复制到hive\lib步骤三
问题1
问题2
ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing 解决办法
ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing 解决办法
步骤4
问题1：跟着教程有时候安不上RMySQL,实在没办法手动导入吧2
R无法安装RMySQL程序包解决方案
问题2：安不上ggplot2
R中命令行安装ggplot2不成功安装一个rstudio在rstudio里面找install,手动安ubantu16如何安装R3.6
