Description

TestDiskBalancerCommand#testPlanNode failed with IllegalArgumentException:

testPlanNode(org.apache.hadoop.hdfs.server.diskbalancer.command.TestDiskBalancerCommand)  Time elapsed: 3.003 sec  <<< ERROR!
java.lang.IllegalArgumentException: Unable to find the specified node. 5417cffa-1bec-4339-8837-1f7c7ba59664

In TestDiskBalancerCommand#testPlanNode, here is incorrect, since the FS is set to be loaded from Json file.

final String planArg = String.format("-%s %s", PLAN,
        cluster.getDataNodes().get(0).getDatanodeUuid());

See the FS loading in TestDiskBalancerCommand#runCommand

FileSystem.setDefaultUri(conf, clusterJson);
