Description

When using a fsimage of Hadoop-2 with hadoop-dynamometer, datanodes fail to start with the following error.

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.apache.hadoop.hdfs.server.datanode.StorageLocation.getUri()Ljava/net/URI; from class org.apache.hadoop.tools.dynamometer.SimulatedDataNodes
        at org.apache.hadoop.tools.dynamometer.SimulatedDataNodes.run(SimulatedDataNodes.java:113)
        at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76)
        at org.apache.hadoop.tools.dynamometer.SimulatedDataNodes.main(SimulatedDataNodes.java:88)
./start-component.sh: line 317: kill: (9876) - No such process

The cause of this error is an incompatibility of StorageLocation.
