Sandeep More commented on KNOX-2540:
------------------------------------

Thanks [~Bing-ok] for filing the bug and detailed analysis! I think approach #1 is better so we don't have to keep track of one more dependency. 
Are you planning on submitting a PR?

> h2. Issue description:
> There are multiple versions of _*org.apache.curator:curator-client*_ in _*hadoop-examples*_. As shown in the following dependency tree, library _org.apache.curator:curator-client:2.13.0 **_ is transitively introduced by _*org.apache.hadoop:hadoop-common:3.2.1*_ , but has been managed to be version _*4.3.0*_.
> However, several methods defined in shadowed version _*org.apache.curator:curator-client:2.13.0*_ are referenced by client project via _*org.apache.hadoop:hadoop-common:3.2.1*_ but missing in the actually loaded version _*org.apache.curator:curator-client:4.3.0*_.
> For instance, the following missing method(defined in _*org.apache.curator:curator-client:2.13.0*_) are actually referenced by *_hadoop-examples_*, which will introduce a runtime error(i.e., "NoSuchMethodError") into _*hadoop-examples*_.
> _*org.apache.curator.utils.ThreadUtils: void checkInterrupted(java.lang.Throwable)*_ is invoked by _*hadoop-examples*_ via the following path:
> {code:java}
> <org.apache.knox.examples.WordCount: void main(java.lang.String[])> knox/hadoop-examples/target/classes
> <org.apache.hadoop.util.GenericOptionsParser: void <init>(org.apache.hadoop.conf.Configuration,java.lang.String[])> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.hadoop.util.GenericOptionsParser: void <init>(org.apache.hadoop.conf.Configuration,org.apache.commons.cli.Options,java.lang.String[])> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.hadoop.util.GenericOptionsParser: boolean parseGeneralOptions(org.apache.commons.cli.Options,java.lang.String[])> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.hadoop.util.GenericOptionsParser: void processGeneralOptions(org.apache.commons.cli.CommandLine)> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.hadoop.security.Credentials: org.apache.hadoop.security.Credentials readTokenStorageFile(org.apache.hadoop.fs.Path,org.apache.hadoop.conf.Configuration)> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.hadoop.io.IOUtils: void cleanupWithLogger(org.slf4j.Logger,java.io.Closeable[])> Respository/org/apache/hadoop/hadoop-common/3.2.1/hadoop-common-3.2.1.jar
> <org.apache.curator.framework.recipes.nodes.PersistentNode: void close()> Respository/org/apache/curator/curator-recipes/4.3.0/curator-recipes-4.3.0.jar
> <org.apache.curator.utils.ThreadUtils: void checkInterrupted(java.lang.Throwable)>{code}
> h2. Suggested fixing solutions:
> 1. Upgrade dependency _*org.apache.hadoop:hadoop-common*_ from _*3.2.1*_ to _*3.2.2*_.Because the newer version _*org.apache.hadoop:hadoop-common:3.2.2*_ does not invoke the above missing methods, such changing can solve the problem.
> This repair will introduce the following new dependencies:
>  javax.activation:javax.activation-api:1.2.0
> 2. Change direct dependency _*org.apache.curator:curator-client*_ from _*4.3.0*_ to _*2.13.0*_.
