Question

请帮助我找出一种使SingleColumnValueFilter正常工作的方法

我的hbase表中有一个计数器列和一个过滤器

 FILTER => 
     SingleColumnValueFilter.new(
         Bytes.toBytes('cf'), Bytes.toBytes('counter'), 
         CompareFilter::CompareOp.valueOf('GREATER'), 
         BinaryComparator.new(Bytes.toBytes(2))
     )

不起作用。示例：

    hbase(main):012:0> scan 'hbase_table', { COLUMNS=>'cf:counter:toInt', LIMIT=>10, 
FILTER => SingleColumnValueFilter.new(Bytes.toBytes('cf'), Bytes.toBytes('counter'), CompareFilter::CompareOp.valueOf('GREATER'), BinaryComparator.new(Bytes.toBytes(2)))}
    ROW                                                          COLUMN+CELL
     0001529652065test162tset450967612             column=cf:counter, timestamp=1529654803958, value=1

但是！过滤器

FILTER => "SingleColumnValueFilter('cf','counter',>,'binary:\x00\x00\x00m')"

起作用

hbase(main):013:0> scan 'hbase_table', { COLUMNS=>'cf:counter:toInt', LIMIT=>10, FILTER => "SingleColumnValueFilter('cf','counter',>,'binary:\x00\x00\x00m')" }

我在做什么错了？

谢谢！

Hbase Shell-SingleColumnValueFilter不适用于整数值
