[FLINK-4177] Harden CassandraConnectorTest This PR (hopefully) resolves the instability issues with the Cassandra connector tests. Changelog: * updated cassandra/driver versions * the `cassandra.yaml` was cleaned up * removed several configuration values that used the default * sorted the remaining settings in alphabetical order * the at-least-once sinks were modified to * properly log exceptions when close() is called * keep track of how many records were not acknowledged yet * the tests were modified to * start the embedded cassandra instance in a separate process * and supply an array of performance related jvm arguments, taken from the cassandra repo * no longer truncate tables; instead every test uses a separate table * wait until a connection could be established to cassandra in a retry-loop instead of waiting for a fixed time * no longer run actual flink jobs * use increased timeouts * clean up temporary files You can merge this pull request into a Git repository by running: $ git pull https://github.com/zentol/flink cass_tmp Alternatively you can review and apply these changes as the patch at: https://github.com/apache/flink/pull/2484.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #2484 ---- commit 64b125343839788530729a2119d1dc92e50e849a Author: zentol <ches...@apache.org> Date: 2016-09-05T09:03:00Z [FLINK-4177] Harden CassandraConnectorTest ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
