Как проверить состояние slave нод кластера hadoop?

Здравствуйте.

У меня есть 3 виртуалки на CentOS 7 c hadoop

hadoop01 - master
hadoop02 - slave1
hadoop03 - slave2

стартую master

[hadoop@hadoop01 ~]$ mr-jobhistory-daemon.sh --config /app/hadoop/etc/hadoop start historyserver

получаю результат

[hadoop@hadoop01 ~]$ jps
29520 JobHistoryServer
29249 NodeManager
28467 NameNode
29557 Jps
29000 ResourceManager
28555 DataNode
28862 SecondaryNameNode

проверяю через web
hadoop01:8088/cluster/nodes

там одна единственная запись
Cluster Metrics

/default-rack	RUNNING	hadoop01:46648	hadoop01:8042	Сб окт 14 01:52:45 +0300 2017		0	0 B	8 GB	0	8	2.8.1
Showing 1 to 1 of 1 entries

также и по
hadoop01:50070/dfshealth.html#tab-datanode

тоже информация только по мастеру

Node	Http Address	Last contact	Capacity	Blocks	Block pool used	Version

64.98 GB

правильно ли что отображается только информация о мастере или все-таки должна быть информация и о slave?
