Hbase 命令小结

1、创建test，如果存在先删除

hbase(main)::> disable 'test'
 row(s) in 1.4250 seconds

hbase(main)::> drop 'test'
 row(s) in 0.5540 seconds

hbase(main)::> create 'test','grade', 'course'
 row(s) in 0.7450 seconds

=> Hbase::Table - test

2、查看数据表

hbase(main)::> list
TABLE
test
 row(s) in 0.0200 seconds

3、查看数据表结构

hbase(main)::> describe 'test'
DESCRIPTION                                                                          ENABLED
 'test', {NAME => 'course', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', REP true
 LICATION_SCOPE => '0', VERSIONS => '1', COMPRESSION => 'NONE', MIN_VERSIONS => '0',
  TTL => 'FOREVER', KEEP_DELETED_CELLS => 'false', BLOCKSIZE => '65536', IN_MEMORY =
 > 'false', BLOCKCACHE => 'true'}, {NAME => 'grade', DATA_BLOCK_ENCODING => 'NONE',
 BLOOMFILTER => 'ROW', REPLICATION_SCOPE => '0', VERSIONS => '1', COMPRESSION => 'NO
 NE', MIN_VERSIONS => '0', TTL => 'FOREVER', KEEP_DELETED_CELLS => 'false', BLOCKSIZ
 E => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}
 row(s) in 0.0630 seconds

4、插入数据

() 加入一行数据,行名称为zkb 列族grad的列名为”” 值位5
hbase(main)::> put 'test','zkb','grade:','5'
 row(s) in 0.0420 seconds
() 给zkb这一行的数据的列族course添加一列<math,>
hbase(main)::> put 'test','zkb','course:math','97'
 row(s) in 0.0270 seconds
() 给zkb这一行的数据的列族course添加一列<art,>
hbase(main)::> put 'test','zkb','course:art','87'
 row(s) in 0.0260 seconds
() 加入一行数据,行名称为baoniu 列族grad的列名为”” 值为4
hbase(main)::> put 'test','baoniu','grade:','4'
 row(s) in 0.0260 seconds
() 给baoniu这一行的数据的列族course添加一列<math,>
hbase(main)::> put 'test','baoniu','course:math','89'
 row(s) in 0.0270 seconds
() 给Jerry这一行的数据的列族course添加一列<art,>
hbase(main)::> put 'test','baoniu','course:art','80'
 row(s) in 0.0270 seconds

5、查看一条数据

hbase(main)::> get 'test','zkb'
COLUMN                            CELL
 course:art                       timestamp=, value=
 course:math                      timestamp=, value=
 grade:                           timestamp=, value=
 row(s) in 0.0200 seconds

6、查看所有数据

hbase(main)::> scan 'test'
ROW                               COLUMN+CELL
 baoniu                           column=course:art, timestamp=, value=
 baoniu                           column=course:math, timestamp=, value=
 baoniu                           column=grade:, timestamp=, value=
 zkb                              column=course:art, timestamp=, value=
 zkb                              column=course:math, timestamp=, value=
 zkb                              column=grade:, timestamp=, value=
 row(s) in 0.0130 seconds

7、指定搜索条件的查询，startrow和stoprow，一般程序开发都使用它

hbase(main)::> scan 'test',{STARTROW=>'baoniu', STOPROW=>'zkb'}
ROW                               COLUMN+CELL
 baoniu                           column=course:art, timestamp=, value=
 baoniu                           column=course:math, timestamp=, value=
 baoniu                           column=grade:, timestamp=, value=
 row(s) in 0.0230 seconds

8、查看指定列的数据

hbase(main)::> scan 'test',{STARTROW=>'baoniu', STOPROW=>'zkb', COLUMNS=>'course'}
ROW                               COLUMN+CELL
 baoniu                           column=course:art, timestamp=, value=
 baoniu                           column=course:math, timestamp=, value=
 row(s) in 0.0160 seconds

9、添加filter

命令行： scan 'nd_shop_rpt_new_d',{STARTROW=>'2014-11-05', STOPROW=>'2014-11-29', FILTER => "( SingleColumnValueFilter('t', 'shop_id', =, 'binary:100705598') AND SingleColumnValueFilter('t', 'auction_id', =, 'binary:42516637646'))"}

hbase(main)::> scan 'nd_shop_rpt_new_d',{STARTROW=>'2014-11-05', STOPROW=>'2014-11-29', FILTER => "( SingleColumnValueFilter('t', 'shop_id', =, 'binary:100705598') AND SingleColumnValueFilter('t', 'auction_id', =, 'binary:42516637646'))"}
ROW                               COLUMN+CELL
--22_100705598_42516637646 column=t:auction_new_time, timestamp=, value=
 --22_100705598_42516637646 column=t:auction_shelf_time, timestamp=, value=-- ::
 --22_100705598_42516637646 column=t:cat_id, timestamp=, value=
 --22_100705598_42516637646 column=t:cat_name, timestamp=, value=
 --22_100705598_42516637646 column=t:seller_id, timestamp=, value=-
 --22_100705598_42516637646 column=t:shop_id, timestamp=, value=
 --22_100705598_42516637646 column=t:thedate, timestamp=, value=--
 --22_100705598_42516637646 column=t:trade_amount, timestamp=, value=
 --22_100705598_42516637646 column=t:trade_amt, timestamp=, value=68.0
 row(s) in 1.4770 seconds
