> 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:

ranger\unixauthclient\target\classes

boolean add(java.lang.Object)> Repositories\org\apache\curator\curator-client\2.12.0\curator-client-2.12.0.jar
> <org.apache.curator.shaded.com.google.common.reflect.TypeToken$TypeFilter$1: boolean
apply(java.lang.Object)> Repositories\org\apache\curator\curator-client\2.12.0\curator-client-2.12.0.jar
> <org.apache.curator.shaded.com.google.common.reflect.TypeToken$TypeFilter$1: boolean
apply(com.google.common.reflect.TypeToken)> Repositories\org\apache\curator\curator-client\2.12.0\curator-client-2.12.0.jar
> <com.google.common.reflect.TypeToken: java.lang.reflect.Type access$400(com.google.common.reflect.TypeToken)>{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.
