[jira] [Created] (FLINK-8980) End-to-end test: BucketingSink

Till Rohrmann created FLINK-8980:
------------------------------------

             Summary: End-to-end test: BucketingSink
                 Key: FLINK-8980
                 URL: https://issues.apache.org/jira/browse/FLINK-8980
             Project: Flink
          Issue Type: Sub-task
          Components: Tests
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
             Fix For: 1.5.0


In order to verify the {{BucketingSink}}, we should add an end-to-end test which verifies that the {{BucketingSink}} does not lose data under failures.

An idea would be to have a CountUp job which simply counts up a counter which is persisted. The emitted values will be written to disk by the {{BucketingSink}}. Now we should kill randomly Flink processes (cluster entrypoint and TaskExecutors) to simulate failures. Even after these failures, the written files should contain the correct sequence of numbers.
