啓動hbase集羣：

bin/start-hbase.sh

啓動hbase shell：

bin/hbase shell

創建數據庫：

create_namespace 'test'

創建表：

create 'test:student', {NAME => 'info', VERSIONS => 3}

添加數據：

put 'test:student', '1001', 'info:name', 'fanghailiang'
put 'test:student', '1002', 'info:name', 'sunyu'
put 'test:student', '1001', 'info:age', '29'
put 'test:student', '1001', 'info:sex', 'mail'

數據刷到hdfs文件系統

flush 'test:student'

查詢數據

scan 'test:student', {COLUMNS => 'info:name'}

刪除數據：

deleteall 'test:student', '1002'
