We are running flink 1.2 in pre production
I am trying to test checkpoint stored in external location in s3
I have set these below in flink-conf.yaml
state.backend: filesystem
state.checkpoints.dir: s3://abc-checkpoint
state.backend.fs.checkpointdir: s3://abc-checkpoint
I get this failure in job manager log
java.lang.Exception: Cannot initialize File System State Backend with URI
's3://abc-checkpoint.

Any clue? I thought as I am using EMR Hadoop to s3 integration is already
working.
Thanks
