Hi ZooKeeper users,

There's an ongoing discussion on the dev list about upgrading the required
Java version to 1.8 on trunk and 3.5 branches.

We'd like to get some feedback from a bigger audience if anybody or any
other component that is dependent on ZooKeeper has any concerns or
objections against the change?

I've quickly checked some of the major components that are heavy Zk clients:

Hadoop/HDFS = 1.8 required
HBase = 1.8 required
Kafka = 1.7 required (has some 1.8 and 1.9 bindings)
Hive = 1.8 required
Curator = 1.7 required (has 1.8-only async module to take advantage of Java
Solr  = 1.8

As always, your feedback is much appreciated.
