Andrey Zagrebin updated FLINK-13019:
------------------------------------
Description:
The simplest IT test is to create a batch job with a sequence of non-parallel
mappers.
The each mapper writes to a blocking partition which means the next mapper
starts when the previous is done.
The mappers are not chained into one Task which makes them separate failover
regions.
