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 rootlocalhost 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
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
