Our job is reading from kinesis stream as a job input. Quiet often when the job is checkpointing for the first time the exception is thrown.

The scenario the produces the exception:

# Upload a new jar file with job logic
# Start new job
# Stop the job with savepoint that is written to s3
# Upload a new jar file with job logic(in this case the jar contains the same code - but our pipeline generates new jar file name for every build)
# Start a new job from savepoint
# The first checkpoint fails causing the job to be cancelled

If the job is started without passing savepoint the checkpointing works fine.

Other information:

Flink version 1.2.1
Beam 2.0.0
Flink Parallelism - 20 slots 
Number of task managers - 4
