list:看看你有啥表

建表：create 'TestTable','cf1','cf2','cf3'

切分表建表：./bin/hbase org.apache.hadoop.hbase.util.RegionSplitter -c 500 TestTable -f cf1:cf2:cf3

修改表属性：

disable 'IndexInfo'(需要先disable)

alter 'IndexInfo', {NAME => 'Author', BLOOMFILTER => 'ROWCOL', REPLICATION_SCOPE => '0', VERSIONS => '2147483647', COMPRESSION => 'LZO', TTL => '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'},
{NAME => 'Board', BLOOMFILTER => 'ROWCOL', REPLICATION_SCOPE => '0', COMPRESSION => 'LZO', VERSIONS => '2147483647', TTL => '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}, {NAME => 'Index', BLOOMFILTER => 'ROWCOL', REPLICATION_SCOPE
=> '0', VERSIONS => '2147483647', COMPRESSION => 'LZO', TTL => '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}, {NAME => 'Tag', BLOOMFILTER => 'ROWCOL', REPLICATION_SCOPE => '0', COMPRESSION => 'LZO', VERSIONS => '2147483647',
TTL => '2147483647', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}

enable 'IndexInfo'

可以看一下常用的设置;P

增加记录（如果重复会追加版本）：put 'TestTable','r1','cf1:cf1_c,' v1'

获取记录（默认获取最新版本）：get 'TestTable','r1'

按照不同版本获取记录：get 'blog','1',{COLUMN => 'author:nickname',VERSIONS => 2}

查看一张表：scan 'TestTable'

删除一个cell：delete 'TestTable','r1','cf1:cf1_c'

删除一行：delete 'TestTable','r1'

删除表：disable 'TestTable'

drop 'TestTable'
