> I am working on a project with Google ads-lib latest version 2.22.0(Dec, 2016), and it requires Guava version 20.0(Oct, 2016). My phoneix-core version is 4.5.2-HBase-0.98. I got the following exception when trying to get Phoenix connection:

> The issue is that from Guava 20.0 Google changed the visibility of com.google.common.collect.Iterators#emptyIterator() from public to default as it was announced earlier to be deprecated.
> I checked several versions of phoenix-core from old to new, looks like all versions are using com.google.common.collect.Iterators#emptyIterator() in org.apache.phoenix.schema.MetaDataClient. So the affected versions should be all.
> Better to replace the usage of emptyIterator() as https://google.github.io/guava/releases/18.0/api/docs/com/google/common/collect/Iterators.html#emptyIterator() recommends.
