打錯命令，按ctrl+Backspace

1.啟動hbase

start-hbase.sh

2.關閉hbase

stop-hbase.sh

3. HBase Shell

是官方提供的一組命令，用于操作HBase。如果配置了HBase的環境變量了，就可以輸入hbase shell 命令進入命令行。

hbase shell

4.help命令

可以通過 help '命名名稱'來查看命令行的具體使用，包括命令的作用和用法。
通過help ‘hbase’ 命名來查看hbase shell 支持的所有命令，hbase將命令進行分組，其中ddl、dml使用較多。

hbase(main):002:0> help 'hbase' ERROR: Invalid command or command group name: hbaseHBase Shell, version 1.4.13, r38bf65a22b7e9320f07aeb27677e4533b9a77ef4, Sun Feb 23 02:06:36 PST 2020 Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command.

5.查看集群狀態status

hbase(main):003:0> status 1 active master, 0 backup masters, 1 servers, 0 dead, 7.0000 average load

6.創建表

#語法 create '表名','列簇名' #例如 hbase(main):014:0> create 'year','info' 0 row(s) in 1.2980 seconds=> Hbase::Table - year

7.插入數據

#語法 put '表名','行鍵','列簇名','值' #例如 # 第一行數據 hbase(main):015:0> put 'year', '1001', 'info:id', '1' 0 row(s) in 0.1320 secondshbase(main):016:0> put 'year', '1001', 'info:name', '張三' 0 row(s) in 0.0070 secondshbase(main):017:0> put 'year', '1001', 'info:age', '28' 0 row(s) in 0.0080 seconds # 第二行數據 hbase(main):026:0> put 'year', '1002', 'info:id', '2' 0 row(s) in 0.0100 secondshbase(main):027:0> put 'year', '1002', 'info:name', '李四' 0 row(s) in 0.0050 secondshbase(main):028:0> put 'year', '1002', 'info:age', '20' 0 row(s) in 0.0040 seconds # 第三行數據 hbase(main):029:0> put 'year', '1003', 'info:id', '3' 0 row(s) in 0.0120 secondshbase(main):030:0> put 'year', '1003', 'info:name', 'wangwu' 0 row(s) in 0.0070 secondshbase(main):031:0> put 'year', '1003', 'info:age', '16' 0 row(s) in 0.0140 seconds

8.查詢數據

scan '表名' hbase(main):032:0> scan 'year' ROW COLUMN+CELL 1001 column=info:age, timestamp=1650518056828, value=28 1001 column=info:id, timestamp=1650518051442, value=1 1001 column=info:name, timestamp=1650518051501, value=\xE5\xBC\xA0\xE4\xB8\x89 1002 column=info:age, timestamp=1650518373828, value=20 1002 column=info:id, timestamp=1650518373023, value=2 1002 column=info:name, timestamp=1650518373053, value=\xE6\x9D\x8E\xE5\x9B\x9B #中文編碼 1003 column=info:age, timestamp=1650518386062, value=16 1003 column=info:id, timestamp=1650518382621, value=3 1003 column=info:name, timestamp=1650518382650, value=wangwu 3 row(s) in 0.0430 seconds

9.掃描列簇

# 語法 scan '表名', {COLUMN=>'列族名'} # 例如 hbase(main):033:0> scan 'year',{COLUMN=>'info'} ROW COLUMN+CELL 1001 column=info:age, timestamp=1650518056828, value=28 1001 column=info:id, timestamp=1650518051442, value=1 1001 column=info:name, timestamp=1650518051501, value=\xE5\xBC\xA0\xE4\xB8\x89 1002 column=info:age, timestamp=1650518373828, value=20 1002 column=info:id, timestamp=1650518373023, value=2 1002 column=info:name, timestamp=1650518373053, value=\xE6\x9D\x8E\xE5\x9B\x9B 1003 column=info:age, timestamp=1650518386062, value=16 1003 column=info:id, timestamp=1650518382621, value=3 1003 column=info:name, timestamp=1650518382650, value=wangwu 3 row(s) in 0.0360 seconds

10.掃描列簇的指定列

14.查看指定行的數據

#語法 get '表名'，'行鍵' #例如 hbase(main):042:0> get 'year','1001' COLUMN CELL info:age timestamp=1650519485027, value=22 info:id timestamp=1650519483672, value=1 info:name timestamp=1650519483706, value=zhangsan 1 row(s) in 0.0310 seconds

15.查看指定列族的列的數據

#語法 get '表名'，'行鍵','列簇名' #例如 hbase(main):043:0> get 'year','1001','info:age' COLUMN CELL info:age timestamp=1650519485027, value=22 1 row(s) in 0.0110 seconds

16.查看行數

#語法 count '表名' #例如 hbase(main):044:0> count 'year' 3 row(s) in 0.0120 seconds=> 3

17.刪除某 rowkey 行鍵的全部數據：

#語法 deleteall '表名'，'行鍵' #例如 hbase(main):045:0> deleteall 'year','1001' 0 row(s) in 0.0520 secondshbase(main):046:0> scan 'year' ROW COLUMN+CELL 1002 column=info:age, timestamp=1650518373828, value=20 1002 column=info:id, timestamp=1650518373023, value=2 1002 column=info:name, timestamp=1650518373053, value=\xE6\x9D\x8E\xE5\x9B\x9B 1003 column=info:age, timestamp=1650518386062, value=16 1003 column=info:id, timestamp=1650518382621, value=3 1003 column=info:name, timestamp=1650518382650, value=wangwu 2 row(s) in 0.0120 seconds

19.列舉所有表list?

hbase(main):051:0> list TABLE year 1 row(s) in 0.0110 seconds=> ["year"]

20.表是否存在exists

# 語法 exists '表名' #例如 hbase(main):052:0> exists 'year' Table year does exist 0 row(s) in 0.0110 seconds

?21.啟用表enable和禁用表disable

通過enable和disable來啟用/禁用這個表,相應的可以通過is_enabled和is_disabled來檢查表是否被禁用。

# 語法 enable '表名' is_enabled '表名'disable '表名' is_disabled '表名' #例如 hbase(main):053:0> enable 'year' 0 row(s) in 0.0190 secondshbase(main):054:0> is_enabled 'year' true 0 row(s) in 0.0100 secondshbase(main):055:0> hbase(main):056:0* disable 'year' 0 row(s) in 2.2670 secondshbase(main):057:0> is_disabled 'year' true 0 row(s) in 0.0320 seconds

22.清空表數據

#語法 先禁用表 才能清空數據 #例如disable 'year'turncate 'year'

23.刪除表

#語法 先禁用表 才能刪除表 #例如disable 'year'drop 'year'
