Task Manager recovery in Standalone Cluster High Availability mode

[F.Amara]

Hi,

I'm working with Apache Flink 1.1.2 and testing on High Availability mode. In the case of Task Manager failures they say a standby TM will recover the work of the failed TM. In my case, I have 4 TM's running in parallel and when a TM is killed the state goes to Cancelling and then to Failed rather than Restarting and the work is not recovered.

Is there a specific way to create standby TM's and a specific reason for jobs not being recovered?

Hey! Did you configure a restart strategy?

Keep in mind that in In stand alone mode a TM process that has exited
won't be automatically restarted though.

Hi,

Thanks a lot for the reply. I configured a restart strategy as suggested and now the TM failure scenario is working as expected. Once a TM is killed another active TM automatically recovers the job.
