    Description

      The reflective access

      Field.class.getDeclaredField("modifiers")

      in HFileSystem.java:334 leads to a warning (and probably error?):

       

      java.lang.NoSuchFieldException: modifiers
	at java.base/java.lang.Class.getDeclaredField(Class.java:2417)
	at org.apache.hadoop.hbase.fs.HFileSystem.addLocationsOrderInterceptor(HFileSystem.java:334)

	at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:1144)
	at foo.Main.main(Main.java:11)

      when running the following code:

       

      public static void main(String[] args) throws Exception {
    HBaseTestingUtility utility = new HBaseTestingUtility(HBaseConfiguration.create());
    utility.startMiniCluster(StartMiniClusterOption.builder().numRegionServers(3).build());
}

      From my knowledge this results from the more restrictive reflection protection of java.base classes in the newer java versions.
