> h1. Issue description
> Hi, there are multiple versions of _*com.google.guava:guava*_ in
> _*ranger\unixauthclient*_. As shown in the following dependency tree,
> according to Maven's “nearest wins” strategy, only
> _*com.google.guava:guava:25.1-jre*_ can be loaded,
> _*com.google.guava:guava:16.0.1*_ will be shadowed.
> However, one method defined in shadowed version
> _*com.google.guava:guava:16.0.1*_ is referenced by client project
> _*org.apache.hadoop:hadoop-auth:3.1.1*_, but missing in the actually loaded
> version _*com.google.guava:guava:25.1-jre*_.
> For instance, the following missing method(defined in
> _*com.google.guava:guava:16.0.1*_) is actually referenced by
> _*ranger\unixauthclient*_, which will introduce a runtime error(i.e.,
> "NoSuchMethodError") into _*ranger\unixauthclient*_.\
> _*Missing method: com.google.common.reflect.TypeToken: java.lang.reflect.Type
> access$400(com.google.common.reflect.TypeToken)*_ is invoked by
> _*ranger\unixauthclient*_ via the following path:
> {noformat}

> h1. Suggested fixing solutions
> 1. Upgrade dependency _*org.apache.hadoop:hadoop-auth*_ from _*3.1.1*_ to
> *_3.3.0_*. Because the newer version _*org.apache.hadoop:hadoop-auth:3.3.0*_
> does not invoke the above missing method, such upgrading can solve the
> problem.
> 2. Change dependency _*com.google.guava:guava*_ from _*25.1-jre*_ to
> *_24.0-jre_*. Because version *_24.0-jre_* includes the above missing method
> and is compatible with other versions of _*com.google.guava:guava*_ .
> Please let me know which solution do you prefer? I can submit a PR to fix it.
> Thank you very much for your attention.
