Hadoop 2.8.1: Why is nodemanager not coming up?

Question

big data

Hello.
I have 3 virtual machines on CentOS 7 with hadoop
hadoop01 - master
hadoop02 - slave1
hadoop03 - slave2
start on master

[[email protected] hadoop]$ /app/hadoop/sbin/start-all.sh
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

hadoop03: starting nodemanager, logging to /app/hadoop/logs/yarn-hadoop-nodemanager-hadoop03.out

I check the list of processes, there is no nodemanager in it

[[email protected] hadoop]$ jps
20657 NameNode
21011 ResourceManager
20855 SecondaryNameNode
21272 Jps
[[email protected] hadoop]$

Why does nodemanager not rise and where can I see the reason?

Answer 1

lifting is provided as follows

hadoop-daemon.sh --config /app/hadoop/etc/hadoop --script hdfs start namenode
hadoop-daemon.sh --config /app/hadoop/etc/hadoop --script hdfs start datanode
/app/hadoop/sbin/start-dfs.sh
yarn-daemon.sh --config /app/hadoop/etc/hadoop  start resourcemanager
yarn-daemon.sh --config /app/hadoop/etc/hadoop  start nodemanager
yarn-daemon.sh --config /app/hadoop/etc/hadoop  start proxyserver
/app/hadoop/sbin/start-yarn.sh
mr-jobhistory-daemon.sh --config /app/hadoop/etc/hadoop start historyserver
