[jira] [Updated] (FLINK-13019) IT test for fine-grained recovery

     [ https://issues.apache.org/jira/browse/FLINK-13019?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrey Zagrebin updated FLINK-13019:
------------------------------------
    Description: The simplest IT test is to create a batch job with a sequence of non-parallel mappers. The mappers write 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.
