Hello,
FLINK-5612 might be a blocker as well; basically if you use the
GlobFilePathFilter in a job, chances are it will fail.
Also, the lastCheckpointSize metric that we collect for each task was
broken when the key-groups were introduced.

Chesnay

Hi Robert,
I found an potientally blocking issue in RC1 that I would like to bring up for
debate. In [FLINK-5602], Ufuk found a NPE that happened during the first
checkpoint after migrating a job from Flink 1.1 to 1.2. I looked into this and
found that the cause of this problem is the absense of namespace serializers in
Flink 1.1 checkpoints. Flink 1.2 always makes all serializers part of the
checkpoint and therefore a precondition to checkpointing fails if a checkpoint
runs before the user code is delivering the namespace serializer. This is a
race condition that (depending on the user code) could fail almost
deterministcally in some situations (e.g. user is registering the state rather
late). The consequence is that checkpointing (and the whole job) fails in this
scenario and potentially prevents user from upgrading to 1.2. I have a open PR
#3200 that is fixing this problem.
Best,
Stefan
