Hi Gordon,
To pile on what Cos said, YARN's ResourceManager also stores it's state in
ZK. See the YARN JIRA
<https://issues.apache.org/jira/browse/MAPREDUCE-279>and design
doc<https://issues.apache.org/jira/secure/attachment/12486023/MapReduce_NextGen_Architecture.pdf>for
more details.
And, adding a dependency like this also allows us to harmonize the version
of zookeeper (which is increasingly becoming a fundamental building block)
being used by various components in the ecosystem.

Mark
