Filter conditions for the Scan command in the Hbase shell Prefixfilter

The filter condition for the scan command in the Hbase Shell Prefixfilter is to filter the Rowkey.

The difference between scan and get is that get gets the data from a row, and scan gets the data from several row, so you can set the filter condition for the rowkey of the scan. Such as:

Scan ' webpage ',{columns=> "info:info",filter=> "Prefixfilter (' Www.alibaba. ')"}

In the previous example, columns is a filter for column families and qualify, you can specify only the column family, or you can specify the column family and qualify;filter=> "Prefixfilter (' Www.alibaba. ')" The Rowkey is prefixed with the filter, Rowkey for www.alibaba.cn and www.alibaba.com data can be matched.
