*What is the issue*
org.apache.beam.sdk.io.kinesis.RoundRobin class is using ArrayDeque class which
is not thread safe. If ConcurrentLinkedDeque deque is used the problem should
be fixed.
was:
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.
