zentol opened a new pull request #9117: [FLINK-13223][dist] Enable fine-grained 
recovery by default in distribution
URL: https://github.com/apache/flink/pull/9117
 
 
   Enables fine-grained recovery by default in the flink distribution. We don't 
enable it by default for all tests since too many tests make implicit 
assumptions about the failover behavior, that is they rely on every task being 
restarted on failure.
   
   Change log:
   * disables `FORCE_PARTITION_RELEASE_ON_CONSUMPTION` as otherwise 
fine-grained recovery cannot really work; this change should be safe for tests
   * sets the failover strategy to "region" in the flink-conf.yaml contained in 
the distribution
   * disables fine-grained recovery in the StreamingFileSink E2E test since it 
relies on global failovers to occur
   
   @KurtYoung @tzulitai I would like to include this in 1.9, as otherwise I 
fear this feature will go largely unnoticed by new users and during testing.
