Package org.apache.hadoop.hbase.fs

Class TestBlockReorderBlockLocation

java.lang.Object

org.apache.hadoop.hbase.fs.TestBlockReorderBlockLocation

public class TestBlockReorderBlockLocation
extends Object

Tests for the hdfs fix from HBASE-6435. Please don't add new subtest which involves starting / stopping MiniDFSCluster in this class. When stopping MiniDFSCluster, shutdown hooks would be cleared in hadoop's ShutdownHookManager in hadoop 3. This leads to 'Failed suppression of fs shutdown hook' error in region server.
