Hi,
I think there is currently no easy way of doing this. Things that come to mind
are:
- looking at the JM log
- polling the JM REST interface for completed externalised checkpoints
The good news is that Flink 1.5 will rework how externalised checkpoints work a
bit: basically, all checkpoints can now be considered externalised and the
metadata will be stored in the root directory of the checkpoint, not in one
global directory for all jobs. This way, the metadata for externalised
checkpoints resides in the checkpoint directory of each job and it should be
reasonably simple to restore from that.
Best,
Aljoscha
