[1/2] flink git commit: [hotfix] Execute YARN integration tests only
upon request (by activating the 'include-yarn-tests' profile)
Repository: flink
Updated Branches:
refs/heads/master 54668242b -> 68c1afc20
[hotfix] Execute YARN integration tests only upon request (by activating the 'include-yarn-tests' profile)
The default Hadoop version set in Flink (2.3.0) is causing the MiniYarnCluster to fail on some machines with some ip/hostname resolution issues.
The YARN tests are all executed in travis profiles with Hadoop versions above 2.3.0
This closes #1210
