The job 0fc94de8d94e123585b5baed6972dbe8 was restored from an externalized
checkpoint generated by +01dbaf21d7c5e8f8eabd3602e086bb89+ and after the
restoration was successful and +0fc94de8d94e123585b5baed6972dbe8+ had generated
new externalized checkpoints I thought it was safe to delete the checkpoints
from +01dbaf21d7c5e8f8eabd3602e086bb89+ but apparently I was wrong.
I have attached the _metadata file from
+/home/anttkaik/flink/checkpoints/0fc94de8d94e123585b5baed6972dbe8/chk-12+
which contains the reference to
+/home/anttkaik/flink/checkpoints/01dbaf21d7c5e8f8eabd3602e086bb89/shared/0a3c0c1d-c924-4e6d-b6ad-463a75c9fce8+.
