我在所有主服务器和从服务器中都拥有$ JAVA_HOME
I have got the $JAVA_HOME in all the master and slaves
]$ echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64/
下面是配置文件设置.
jobmanager.rpc.address: 10.0.2.4
# The RPC port where the JobManager is reachable.
jobmanager.rpc.port: 6123
taskmanager.numberOfTaskSlots: 5
parallelism.default: 2
主控中的JPS:
]# jps
30944 QuorumPeerMain
9600 StandaloneSessionClusterEntrypoint
31640 ConsoleProducer
32889 Jps
31278 Kafka
在从属服务器中，我看不到jps命令输出:
in slave I am not able to see jps command output:
# jps
-bash: jps: command not found
在任务管理器下，我也看不到任何条目. http://10.xxx:8081/#/task-manager
Also under the task-manager i don't see any entries.http://10.x.x.x:8081/#/task-manager
推荐答案
您是否配置了conf/slaves文件?参见 https://ci .apache.org/projects/flink/flink-docs-stable/ops/deployment/cluster_setup.html#configuring-flink .
Did you configure the conf/slaves file? See https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/cluster_setup.html#configuring-flink.
jps的问题看起来不像Flink的问题.从站上真的有一个JDK吗?
The problem with jps doesn't look like a problem with Flink. Is there really a JDK on the slave?
