Class TestFilter.SlowScanFilter

java.lang.Object

org.apache.hadoop.hbase.filter.Filter

org.apache.hadoop.hbase.filter.FilterBase

org.apache.hadoop.hbase.filter.TestFilter.SlowScanFilter

Enclosing class:

TestFilter

public static class TestFilter.SlowScanFilter
extends org.apache.hadoop.hbase.filter.FilterBase

Filter which makes sleeps for a second between each row of a scan. This can be useful for manual testing of bugs like HBASE-5973. For example: create 't1', 'f1' 1.upto(100) { |x| put 't1', 'r' + x.to_s, 'f1:q1', 'hi' } import org.apache.hadoop.hbase.filter.TestFilter scan 't1', { FILTER => TestFilter::SlowScanFilter.new(), CACHE => 50 }
