hbase shell 杂记

规划：nn1.hadoop   nn2.hadoop   s1.hadoop   s2.hadoop

ZK：                    nn1    nn2    s1
journalnode:        nn1   nn2    s1
DataNode:           nn1    nn2   s1   s2
NodeManager:    nn1   nn2   s1   s2
NameNode:          nn1    nn2
ResourceManager:   s1   s2
zkfc :                    nn1  nn2

yum -y install svn ncurses-devel gcc* lzo-devel zlib-devel autoconf automake libtool cmake openssl-devel bzip2

启动顺序：

zkServer.sh start 　　　　　　 // nn1 nn2 s1
hadoop-daemon.sh start journalnode 　　　　//nn1 nn2 s1

namenode（nn1.hadoop）节点进行格式化
hadoop namenode -format 　　　　 //nn1
cd /data
scp -r hadoopdata/ nn2.hadoop:$PWD

格式化zkfc //nn1
hdfs zkfc -formatZK

启动HDFS //nn1
start-dfs.sh 或者 hadoop-daemon.sh start namenode

nn2:
hadoop namenode -bootstrapStandby
hadoop-daemon.sh start namenode

s1/s2:
hadoop-daemon.sh start datanode

s2
start-yarn.sh //NodeManager

s1
yarn-daemon.sh start resourcemanager //resourcemanager
yarn-daemon.sh stop resourcemanager

nn1
start-yarn.sh
stop-yarn.sh

nn1 启动 mapreduce 任务历史服务器
mr-jobhistory-daemon.sh start historyserver

查看各主节点的状态
HDFS:
hdfs haadmin -getServiceState nn1
hdfs haadmin -getServiceState nn2

YARN:
yarn rmadmin -getServiceState rm1
yarn rmadmin -getServiceState rm2

hadoop-daemon.sh start namenode
hadoop-daemon.sh stop namenode

hadoop-daemon.sh start datanode
hadoop-daemon.sh stop datanode

创建目录
hdfs dfs -mkdir /hadoop/

上传文件
hadoop fs -put /opt/tools/CentOS-7-x86_64-Minimal-1908.iso /hadoop/
hadoop fs -ls /hadoop/

删除
hdfs dfs -rmr /hadoop/CentOS-7-x86_64-Minimal-1908.iso

HBase介绍
https://www.cnblogs.com/qingyunzong/p/8665698.html

#HBase
export HBASE_HOME=/usr/local/hbase-1.3.6
export PATH=$PATH:$HBASE_HOME/bin

sudo chown -R hadoop:hadoop hbase-1.3.6
sudo ln -s hbase-1.3.6 hbase

http://192.168.80.166:16010/master-status

http://192.168.80.169:16000/master-status

手动启动 HBASE
hbase-daemon.sh start master
hbase-daemon.sh start regionserver

hbase help
help "create"
help "dml"
help "get"
help 'list'

表的操作包括（创建create，查看表列表list。查看表的详细信息desc，删除表drop，清空表truncate，修改表的定义alter）

>create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}

创建：
>create 'myHbase',{NAME => 'myCard',VERSIONS => 5}

>list

查看结构
>desc 'myHbase'

修改
>alter 'myHbase', NAME => 'myInfo'

删除
>alter 'myHbase', NAME => 'myCard', METHOD => 'delete'

删除一个列簇
>alter 'myHbase', 'delete' => 'myCard'

添加列簇hehe同时删除列簇myInfo
> alter 'myHbase', {NAME => 'hehe'}, {NAME => 'myInfo', METHOD => 'delete'}

清空
>truncate 'myHbase'

删除表
>disable 'myHbase'
> drop 'myHbase'

HBase表中数据的操作
数据的操作（增put，删delete，查get + scan, 改==变相的增加）

>create 'user_info',{NAME=>'base_info',VERSIONS=>3 },{NAME=>'extra_info',VERSIONS=>1 }
>put 'user_info', 'user0001', 'base_info:name', 'zhangsan1'
