Ceph configuration for checkpoints?

Hello people,

I'm looking for the configuration options required to use Ceph as a backend
for checkpoints.

So far, I can see that `state.backend.fs.checkpointdir` and
`state.checkpoints.dir` should be something like
`ceph:///my-checkpoint-bucket`. But where do I define server and acess and
secret keys? I couldn't find anything remotely related to that in the
docs...

Hello Julio,

how we deploy Ceph:

1) make sure Ceph is mounted through all the nodes that make up your Flink
cluster; ensure path(s) are the same for each node
2) simply reference the Ceph mountpoint(s) via file://<your path>

Hi,

Have you tried to refer to ceph documentation? http://docs.ceph.com/docs/jewel/cephfs/hadoop/ <http://docs.ceph.com/docs/jewel/cephfs/hadoop/> It claims to be:

> a drop-in replacement for the Hadoop File System (HDFS)

So I would first try to configure ceph according to their documentation and try to use Flink’s built in Hadoop connector.
