Tsuyoshi Ozawa commented on HADOOP-14284:
-----------------------------------------
Attaching v10 patch. Summary:
* (from v7) Creating hadoop-shaded-thirdparty which includes shaded Guava.
However, it doesn't include com.google.common.base.Function, Predicate, and
TypeToken. It's because the classes are required to use Apache Curator:
https://cwiki.apache.org/confluence/display/CURATOR/TN13
* (from v7) Using Guava in
hadoop-shaded-thirdparty(org.apache.hadoop.com.google.common) in server-side
code instead of non-shaded Guava directly. This change subsumes what
HADOOP-14238 is addressing.
* (from v10) Shading Guava inside hadoop-client-modules to shade all Guava
unlike hadoop-shaded-thirdparty.

> HADOOP-10101 upgraded the guava version for 3.x to 21.
> Guava is broadly used by Java projects that consume our artifacts.
> Unfortunately, these projects also consume our private artifacts like
> {{hadoop-hdfs}}. They also are unlikely on the new shaded client introduced
> by HADOOP-11804, currently only available in 3.0.0-alpha2.
> We should shade Guava everywhere to proactively avoid breaking downstreams.
> This isn't a requirement for all dependency upgrades, but it's necessary for
> known-bad dependencies like Guava.
