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：

步骤二

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

我的source.list,换成我的源，把原来的改个名，万一出错了还能改回来

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran35/

安装R3.6以及Rstudio：

---------r3.6的安装--------
#第一步下载公钥
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 51716619E084DAB9
#更新软件源
sudo apt-get update
#安装
sudo apt install --no-install-recommends r-base
-------rstudio的安装---------
sudo apt-get install gdebi-corewget https://download2.rstudio.org/rstudio-server-1.0.136-amd64.debsudo gdebi rstudio-server-1.0.136-amd64.debrstudio-server start
