java.lang.Object

org.apache.hadoop.hbase.regionserver.HRegion

org.apache.hadoop.hbase.regionserver.TestScannerHeartbeatMessages.HeartbeatHRegion

All Implemented Interfaces:

org.apache.hadoop.hbase.conf.ConfigurationObserver, org.apache.hadoop.hbase.conf.PropagatingConfigurationObserver, org.apache.hadoop.hbase.io.HeapSize, org.apache.hadoop.hbase.regionserver.Region

Enclosing class:

TestScannerHeartbeatMessages

private static class TestScannerHeartbeatMessages.HeartbeatHRegion
extends org.apache.hadoop.hbase.regionserver.HRegion

Custom HRegion class that instantiates RegionScanners with configurable sleep times between fetches of row Results and/or column family cells. Useful for emulating an instance where the server is taking a long time to process a client's scan request
