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

             Summary: Flink runtime test failed caused by curator dependency conflicts
                 Key: FLINK-10943
                 URL: https://issues.apache.org/jira/browse/FLINK-10943
             Project: Flink
          Issue Type: Improvement
          Components: Build System, Tests
    Affects Versions: 1.6.2, 1.5.5
            Reporter: Paul Lin
         Attachments: org.apache.flink.runtime.zookeeper.ZooKeeperStateHandleStoreTest.txt

Hadoop-common of 2.6 + version includes curator dependencies, which would have conflicts with the curator used by Flink runtime and cause test failures (the attachment is the surefire report). 

Note that the curator-recipes dependency introduced in hadoop-common (of flink-shaded-hadoop2) is omitted because the same dependency that exists in the flink-shaded-curator module has a shorter path to the dependency root, but the curator-client dependencies in these two modules have the same length of path, just as below:

```

flink-shaded-hadoop2 -> hadoop-common -> curator-client & curator-recipes

flink-shaded-curator -> curator-recipes -> curator-client

```

So maven would pick the first curator-client, the one in flink-shaded-hadoop2.

To fix this problem I think we can simply exclude curator-client from flink-shaded-hadoop2 dependency in flink-runtime, or switch the dependency to flink-shaded-hadoop which has relocated its curator dependencies.

I'd like to fix this problem, please let me know what you think. Thanks!
