-------------------------------------

             Summary: AbstractOperatorRestoreTestBase can deadlock if one test fails
                 Key: FLINK-12915
                 URL: https://issues.apache.org/jira/browse/FLINK-12915
             Project: Flink
          Issue Type: Bug
          Components: API / Type Serialization System, Tests
    Affects Versions: 1.9.0
            Reporter: Till Rohrmann


The {{AbstractOperatorRestoreTestBase}} can deadlock in case of a failing test case. The problem is that if one test fails then the corresponding test job won't be canceled. Due to that a succeeding test case might not get enough slots to execute because the job of the failing test is still running. This leads to a deadlocked test as happened here: https://api.travis-ci.org/v3/job/548181384/log.txt

A side effect is that the original test failure won't be properly displayed.
