hbase操作语句-03.docx

1、创建一个名为 test 的表，这个表只有一个 column family 为 cf

hbase(main):003:0> create   'test','cf' 0 row(s) in 3.7990 seconds

 2、列出所有的表来检查创建情况

hbase(main):006:0> list TABLE                                                                             test                                                                              1 row(s) in 0.0380 seconds

 3、插入一行，行key为row1, 列为 cf:a， 值是 value1

Hbase中的列是由 column family前缀和列的名字组成的，以冒号间隔。例如这一行的列名就是a.

hbase(main):007:0> put 'test', 'row1',   'cf:a', 'value1' 0 row(s) in 0.1230 seconds   hbase(main):008:0> hbase(main):010:0> put 'test', 'row2',   'cf:b', 'value2' 0 row(s) in 0.0160 seconds hbase(main):011:0> put 'test', 'row3',   'cf:b', 'value3' 0 row(s) in 0.0070 seconds

 4、检查插入情况

1）、Scan这个表

hbase(main):012:0> scan 'test' ROW                     COLUMN+CELL                                                  row1                 column=cf:a,   timestamp=1433923693891, value=value1           row2                 column=cf:b,   timestamp=1433923868853, value=value2           row3                 column=cf:b,   timestamp=1433923881677, value=value3          3 row(s) in 0.0820 seconds   hbase(main):013:0>

 2）、Get一行

hbase(main):013:0> get 'test', 'row1' COLUMN                  CELL                                                         cf:a                 timestamp=1433923693891,   value=value1                     1 row(s) in 0.0190 seconds

 3）、disable 再 drop 这张表

disable 再 drop 这张表，可以清除你刚刚的操作。

hbase(main):014:0> scan 'test' ROW                     COLUMN+CELL                                                  row1                 column=cf:a,   timestamp=1433923693891, value=value1           row2                 column=cf:b,   timestamp=1433923868853, value=value2           row3                 column=cf:b,   timestamp=1433923881677, value=value3          3 row(s) in 0.0270 seconds   hbase(main):015:0> list TABLE                                                                             test                                                                             1 row(s) in 0.0280 seconds   hbase(main):016:0> disable 'test' 0 row(s) in 1.1470 seconds   hbase(main):017:0> scan 'test' ROW                     COLUMN+CELL                                                   ERROR:   org.apache.hadoop.hbase.DoNotRetryIOException: test is disabled. hbase(main):018:0> list TABLE                                                                              test                                                                              1 row(s) in 0.0240 seconds   hbase(main):019:0>   hbase(main):019:0> drop 'test' 0 row(s) in 1.0980 seconds   hbase(main):020:0> list TABLE                                                                             0 row(s) in 0.0180   seconds   hbase(main):021:0>
