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

             Summary: Harden End-to-end tests against download failures
                 Key: FLINK-9802
                 URL: https://issues.apache.org/jira/browse/FLINK-9802
             Project: Flink
          Issue Type: Improvement
          Components: Tests
    Affects Versions: 1.5.0, 1.6.0
            Reporter: Chesnay Schepler


Several end-to-end tests download libraries (kafka, zookeeper, elasticsearch) to set them up locally for testing purposes. Currently, (at least for the elasticsearch test), we do not guard against failed downloads.

We should do a sweep over all tests and harden them against download failures, by retrying the download on failure, and explicitly exiting if the download did not succeed after N attempts.
