Subject [jira] [Commented] (HDFS-12384) Fixing compilation issue with BanDuplicateClasses
Date Sat, 02 Sep 2017 17:31:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151549#comment-16151549
] 

Íñigo Goiri commented on HDFS-12384:
------------------------------------

Thanks [~busbey]. I tried excluding {{curator-framework}} from {{hadoop-client-minicluster}}:
{code}
        <exclusion>
          <groupId>org.apache.curator</groupId>
          <artifactId>curator-framework</artifactId>
        </exclusion>
{code}

And now I get:
{code}
  Found in:
    org.apache.hadoop:hadoop-client-api:jar:3.0.0-beta1-SNAPSHOT:compile
    org.apache.hadoop:hadoop-client-minicluster:jar:3.0.0-beta1-SNAPSHOT:compile
  Duplicate classes:
    org/apache/hadoop/yarn/server/timeline/security/TimelineAuthenticationFilterInitializer.class
    org/apache/hadoop/hdfs/protocolPB/package-info.class
    org/apache/hadoop/yarn/server/timeline/security/TimelineAuthenticationFilter.class

  Found in:
    org.apache.hadoop:hadoop-client-minicluster:jar:3.0.0-beta1-SNAPSHOT:compile
    org.apache.hadoop:hadoop-client-runtime:jar:3.0.0-beta1-SNAPSHOT:compile
  Duplicate classes:
    org/apache/hadoop/shaded/org/apache/curator/framework/api/DeleteBuilder.class
    org/apache/hadoop/shaded/org/apache/curator/framework/CuratorFramework.class
    org/apache/hadoop/shaded/org/apache/curator/framework/api/Backgroundable.class
    org/apache/hadoop/shaded/org/apache/curator/framework/imps/NamespaceWatchedEvent.class
    org/apache/hadoop/shaded/org/apache/curator/framework/api/GetChildrenBuilder.class
    org/apache/hadoop/shaded/org/apache/curator/framework/imps/SetACLBuilderImpl$2.class
    ...
{code}

So now more curator dependencies show as dup and new stuff from TS showed up.
Any idea?
