--------------------------------
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:

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!
