初试Hbase
1. 进入 shell
hbase shell
2. 查看所有库
list
3. 查看表结构
describe 'userInfo'
DESCRIPTION ENABLED
{NAME => 'userInfo', FAMILIES => [{NAME => 'm', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'NONE', true
REPLICATION_SCOPE => '0', VERSIONS => '3', COMPRESSION => 'NONE', MIN_VERSIONS => '0', TTL => '21474
83647', KEEP_DELETED_CELLS => 'false', BLOCKSIZE => '65536', IN_MEMORY => 'false', ENCODE_ON_DISK =>
'true', BLOCKCACHE => 'true'}]}
4. 查询
scan 'userInfo' , {LIMIT => 20} ## 必须大写
get 'userInfo' ,'10001949'
hbase(main):005:0> get 'userInfo' ,'17335912'
