yiheng opened a new pull request #256: [LIVY-708][Server] Align curator jars version
URL: https://github.com/apache/incubator-livy/pull/256
 
 
   ## What changes were proposed in this pull request?
   Livy server has dependency of Apache Curator through hadoop client. However, the versions of the curator jars are not aligned. Here're the curator jars after build
   
   * curator-client-2.7.1.jar
   * curator-framework-2.7.1.jar
   * curator-recipes-2.6.0.jar
   This will cause Method not found issue in some case:
   ```
   Exception in thread "main" java.lang.NoSuchMethodError:
   org.apache.curator.utils.PathUtils.validatePath(Ljava/lang/String;)V
   ```
   This patch specify the version of curator-recipes to 2.7.1. 
   
   ## How was this patch tested?
   Manually test in the env where no such method exception are thrown.
