-------------------------------------
Summary: Tried to associate with unreachable remote address
Key: FLINK-29116
URL: https://issues.apache.org/jira/browse/FLINK-29116
Project: Flink
Issue Type: Bug
Affects Versions: kubernetes-operator-1.1.0, 1.15.1
Reporter: geonyeong kim
Attachments: Screen Shot 2022-08-26 at 5.04.37 PM.png
Hello.
I am planning to distribute and use FlinkDeployment through the flink
kubernetes operator.
CRD, operator, webbook, etc. are all set up, and we actually distributed
FlinkDeployment to confirm normal operation.
*However, strangely, connecting to resource manager fails if you make more than
one task manager pod replica.*
I thought it might be a problem with akka, timeout, etc. so I increased the
values as below
The connection continues to fail.
- akka.retry-gate-closed-for: 10000
- akka.server-socket-worker-pool.pool-size-min: 6
- akka.server-socket-worker-pool.pool-size-max: 10
- akka.client-socket-worker-pool.pool-size-max: 10
- akka.client-socket-worker-pool.pool-size-min: 6
- blob.client.connect.
The log of the taskmanager is as follows.
{code:java}
Association with remote system [akka.tcp://flink@10.238.80.92:6123] has failed,
address is now gated for [10000] ms. Reason: [Disassociated]
Could not resolve ResourceManager address
akka.tcp://flink@10.238.80.92:6123/user/rpc/resourcemanager_1, retrying in
10000 ms: Could not connect to rpc endpoint under address
akka.tcp://flink@10.238.80.92:6123/user/rpc/resourcemanager_1.
Tried to associate with unreachable remote address
[akka.tcp://flink@10.238.80.92:6123]. Address is now gated for 10000 ms, all
messages to this address will be delivered to dead letters. Reason: [The remote
system has quarantined this system. No further associations to the remote
system are possible until this system is restarted.]
{code}
*If you go into the task manager pod and tcp check, the connection is open.*
*Below are the flink versions I used.*
*- flink image: 1.15.1*
*- flink kubernetes operator: 1.1.0*
*I would appreciate it if you could check the problem quickly.*
*If it's a bug, please tell me how to detour in the current situation.*
