bshashikant commented on issue #576: HDDS-2716. Add integration test to verify pipeline closed on read statemachine failure URL: https://github.com/apache/hadoop-ozone/pull/576#issuecomment-591943391 > Hi @adoroszlai, I am not able to repro this problem and the test exception trace is not sufficient to identify what is wrong: > java.io.IOException: INTERNAL_ERROR org.apache.hadoop.ozone.om.exceptions.OMException: Allocated 0 blocks. Requested 1 blocks > @bharatviswa504 any idea if a recent regression was introduced? Thanks @swagle for continuing with this and @adoroszlai for testing it out. @swagle , Let's add a container creation call to the after creating the ozone key and before shutting down the datanode and use ContainerTestHelper.isRatisFollower/isRatisLeader Api to selectively shhutdown dn in the test instead of relying on the leader info from the pipeline object.. Creating the container before writing data will make sure the pipeline is healthy and way before writing and using dn to determine the ratis role will always ensure you are shutting down a follower always rather than relying on scm to tell which may be outdated?
