gameking created FLINK-15074:
--------------------------------
Summary: Connection timed out, Standalone
Key: FLINK-15074
URL: https://issues.apache.org/jira/browse/FLINK-15074
Project: Flink
Issue Type: Bug
Components: Runtime / Network
Affects Versions: 1.9.1
Environment: flink version : 1.5.1 , 1.9.1
jdk version : 1.8.0_181
Number of servers : 15
Number of taskmanagers : 178
Number of slots: 178
Reporter: gameking
Attachments: flink-conf.yaml, jobmanager.log, taskmanager.log
I am running a flink streaming application on a standalone-cluster.
It works well when the job's parallelism is low, just like 96.
But when I try to increase job's parallelism to a high value, like 164 or
more, Job will fail in 10-15 minutes due to connection timeout error
I have try to solve this problem by increaseing taskmanager configs just like
'taskmanager.network.netty.server.numThreads',
'taskmanager.network.netty.client.numThreads',
'taskmanager.network.request-backoff.max', 'akka.ask.timeout' and so on, It
doesn't work.
I also try to change different versions of flink, such as 1.5.1 and 1.9.1, to
solve this problem , it doesn't help too.
Does anyone know how to fix this problem，I have no idea now. It looks like a
bug.
I hava upload my config and log as attachment, and the error trace below ：
