Flink 1.7.2: Task Manager not able to connect to Job Manager

[HarshithBolar]

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor                       

        - Association with remote system [akka.tcp://flink@cluster:22671] has failed, address is now gated for [50] ms. Reason: [Association failed with [akka.tcp://flink@cluster:22671]] Caused by: [cluster: Name or service not known]

 

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith

Hi Harshith,

Can you share JM and TM logs?

Best,

Gary

Hi Gary,

 

I’ve attached the relevant portions of the JM and TM logs.

Hi Harshith,

 

Can you share JM and TM logs?

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Best,
Gary

Hi Harshith,

 

Can you share JM and TM logs?

 

Best,

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor                       

        - Association with remote system [akka.tcp://flink@cluster:22671] has failed, address is now gated for [50] ms. Reason: [Association failed with [akka.tcp://flink@cluster:22671]] Caused by: [cluster: Name or service not known]

 

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith

Hi Gary,

 

Here are the full job manager and task manager logs. In the job manager logs, I see it says “starting StandaloneSessionClusterEntrypoint”, whereas in Flink 1.4.2, it used to say “starting JobManager”. Is this correct?

 

Job manager logs: https://paste.ubuntu.com/p/DCVzsQdpHq/ (https://paste(.)ubuntu(.)com/p/DCVzsQdpHq /)

Task Manager logs: https://paste.ubuntu.com/p/wbvYFZxdT8/ (https://paste(.)ubuntu(.)com/p/wbvYFZxdT8/)

 

Thanks,

Harshith

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Best,
Gary

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor                       

        - Association with remote system [akka.tcp://flink@cluster:22671] has failed, address is now gated for [50] ms. Reason: [Association failed with [akka.tcp://flink@cluster:22671]] Caused by: [cluster: Name or service not known]

 

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith

Hi Gary,

 

An update. I noticed the line “–host cluster” in the program arguments section of the job manager logs. So, I commented the following section in jobmanager.sh, the task manager is now able to connect to job manager without issues.

 

  if [ ! -z $HOST ]; then

        args+=("--host")

        args+=("${HOST}")

fi

Hi Gary,

 

Here are the full job manager and task manager logs. In the job manager logs, I see it says “starting StandaloneSessionClusterEntrypoint”, whereas in Flink 1.4.2, it used to say “starting JobManager”. Is this correct?

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Best,
Gary

Hi Harshith,

In the jobmanager.sh script, the 2nd argument is assigned to the HOST variable
[1]. How are you invoking jobmanager.sh? Prior to 1.5, the script expected an
execution mode (local or cluster) but this is no longer the case [2].

Best,
Gary

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Best,
Gary

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith

Hi Harshith,

In the jobmanager.sh script, the 2nd argument is assigned to the HOST variable
[1]. How are you invoking jobmanager.sh? Prior to 1.5, the script expected an
execution mode (local or cluster) but this is no longer the case [2].

Hi Gary,

 

An update. I noticed the line “–host cluster” in the program arguments section of the job manager logs. So, I commented the following section in jobmanager.sh, the task manager is now able to connect to job manager without issues.

 

  if [ ! -z $HOST ]; then

        args+=("--host")

        args+=("${HOST}")

fi

Hi Gary,

 

Here are the full job manager and task manager logs. In the job manager logs, I see it says “starting StandaloneSessionClusterEntrypoint”, whereas in Flink 1.4.2, it used to say “starting JobManager”. Is this correct?

 

Job manager logs: https://paste.ubuntu.com/p/DCVzsQdpHq/ (https://paste(.)ubuntu(.)com/p/DCVzsQdpHq /)

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith

Hi Gary,

 

The job manager was indeed being invoked with a second parameter.

 

${Flink_HOME}/bin/jobmanager.sh start cluster

 

I removed the second argument and everything works fine now. I really appreciate your help. Thanks a lot :-)

 

Regards,

Harshith

Hi Harshith,

In the jobmanager.sh script, the 2nd argument is assigned to the HOST variable
[1]. How are you invoking jobmanager.sh? Prior to 1.5, the script expected an
execution mode (local or cluster) but this is no longer the case [2].

Hi Gary,

 

An update. I noticed the line “–host cluster” in the program arguments section of the job manager logs. So, I commented the following section in jobmanager.sh, the task manager is now able to connect to job manager without issues.

 

  if [ ! -z $HOST ]; then

        args+=("--host")

        args+=("${HOST}")

fi

Hi Gary,

 

Here are the full job manager and task manager logs. In the job manager logs, I see it says “starting StandaloneSessionClusterEntrypoint”, whereas in Flink 1.4.2, it used to say “starting JobManager”. Is this correct?

 

Job manager logs: https://paste.ubuntu.com/p/DCVzsQdpHq/ (https://paste(.)ubuntu(.)com/p/DCVzsQdpHq /)

Hi Harshith,

The truncated log is not enough. Can you share the complete logs? If that's
not possible, I'd like to see the beginning of the log files where the cluster
configuration is logged.

The TaskManager tries to connect to the leader that is advertised in
ZooKeeper. In your case the "cluster" hostname is advertised which hints a
problem in your Flink configuration.

Best,
Gary

Hi Harshith,

 

Can you share JM and TM logs?

 

Best,

Gary

Hi all,

 

I'm trying to upgrade our Flink cluster from 1.4.2 to 1.7.2

 

When I bring up the cluster, the task managers refuse to connect to the job managers with the following error.

 

        2019-03-14 10:34:41,551 WARN  akka.remote.ReliableDeliverySupervisor                       

        - Association with remote system [akka.tcp://flink@cluster:22671] has failed, address is now gated for [50] ms. Reason: [Association failed with [akka.tcp://flink@cluster:22671]] Caused by: [cluster: Name or service not known]

 

Now, this works correctly if I add the following line into the /etc/hosts file.

 

        x.x.x.x job-manager-address.com cluster

 

Why is Flink 1.7.2 connecting to JM using cluster in the address? Flink 1.4.2 used to have the job manager's address instead of the word cluster.

 

Thanks,

Harshith
