I'm trying to create simple multi node flink cluster (1 master 1 slave). When I start my cluster using "./bin/start-cluster.sh", both job manager and task manager are started, but the task manager is not able to register at the job manager. After few minutes of trying, the task manager dies.
Details about the environment:
- I'm working with Google cloud VMs. OS is Ubuntu x86_64
- tried with flink versions flink-1.7.2 and flink-1.8.0. Both gave the same error.
job manager hostname = ubuntu-test-1 (10.142.0.40)
task manager hostname = ubuntu-test-2 (10.142.15.250)
$ cat conf/flink-conf.yaml:
env.java.home: /opt/sample/include/jdk
jobmanager.rpc.address: 10.142.0.40
jobmanager.rpc.port: 6123
jobmanager.heap.size: 1024m
taskmanager.heap.size: 1024m
taskmanager.numberOfTaskSlots: 1
parallelism.default: 1
rest.port: 8081
$cat conf/masters
10.142.0.40:8081
$ cat conf/slaves
10.142.15.250
Below is the complete log from task manager:
