内容简介
一、HBase Shell操作
一、HBase Shell 操作
1.扫描查看表数据
hbase ( main ):008:0> scan”student”
hbase ( main ):009:0> scan “student” , {SТARTROW=>& “1001” , STOPROW=>
“1001”}
hbase ( main ):010:0> scan “student” , {STARTROW=>＂1001 ” }
2.查看表结构
hbase ( main ):011:0> describe
3.更新指定字段的数据
hbase (main ):012:0> put “student “ , “1001" , “info : name”, “ Nick”
hbase ( main ):013:0> put “student “ ,”1001” , “ info : age” , “100”
4.查看“指定行”或“指定列族;列的数据
hbase ( main ):014:0> get “student “ , “1001”
hbase ( main ):015:0> get “student “ , “1001” , “info : name “
5.统计表数据行数
hbase ( main ):021:0> count“student”
6.制除数据
删除某rowkey 的全部数据
hbase (main ):016:0>deleteal1“student “ , “1001”
删除某 rowkey 的某一列数据:
hbase ( main ):017:0> delete “ student “ , “1002” , “ info :sех”
7.清空表数据
hbase ( main ):018:0> truncate “student “
提示:清空表的操作顺序为先 disable ,然后再 truncate
