apache-flink - flink 集群启动错误 [ERROR] 无法正确获取 JVM 参数

Question

$ bin/start-cluster.sh
Starting cluster.
[INFO] 1 instance(s) of standalonesession are already running on centos1.
Starting standalonesession daemon on host centos1.
[ERROR] Could not get JVM parameters properly.
[ERROR] Could not get JVM parameters properly.

我在所有的主从中都得到了 $JAVA_HOME

]$ 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

母版中的 JPS:

]# jps
30944 QuorumPeerMain
9600 StandaloneSessionClusterEntrypoint
31640 ConsoleProducer
32889 Jps
31278 Kafka

在奴隶我看不到 jps 命令输出:

# jps
-bash: jps: command not found

同样在任务管理器下，我看不到任何条目。

您是否配置了 conf/slaves 文件？见 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。从机上真的有JDK吗？
