Hey,
we are running Flink 1.3.2 with streaming jobs and we are running into
issues when we are restarting a complete job (which can happen due to
various reasons: upgrading of the job, restarting of the cluster,
failures). The problem is that there is no automated way to find out
from which checkpoint-metadata (so externalized checkpoint) we should
resume. There can always be the situation that we are left with multiple
of those files: Now you want to use the most recent one which is
successfully written.
Is there any tooling available already which picks the latest good
checkpoint? Or at least a tool/commandline which we can use to validate
that a checkpoint is valid so we can pick the latest one?
How are others handling this? Manually?
Would be happy to get some input there,
Dominik
