2.filter 过滤部分

PrefixFilter:rowKey前缀过滤

scan 'ecpcibimbqm:lijieran',{FILTER=>"PrefixFilter('003')"}

hbase(main):001:0> scan 'ecpcibimbqm:lijieran',{FILTER=>"PrefixFilter('003')"}
ROW                                COLUMN+CELL

QualifierFilter:列过滤器

QualifierFilter对列的名称进行过滤，而不是列的值。

ROW                                COLUMN+CELL
