Checkpointing and save pointing

[Boris Lublinsky]

I am planning to use external volume for this. My understanding is that it needs to be mounted only to the job manager, not the task managers. Is this correct, or it needs to be mounted to both?

Hi, Boris

TM will also need to write to the external volume.

Best, Congxian

Hi Boris,

Is your question is in the context of replacing Zookeeper by a different service for highly-available setups or are you setting up a regular Flink cluster?

For now is a regular Link cluster,

But even there I want to use both check and save pointing.

We do not want to use Hadoop, but rather shared fs - NFS/Gluster.

I was trying to see whether volumes need to be mounted only for Job manager or both.

HA is the next step. Trying to find the code saving checkpointing location.

For checkpoints and savepoints, the JM and all TMs need access to the same storage system.

This can be shared NFS that is mounted on each machine.
