Key: PHOENIX-3556
URL: https://issues.apache.org/jira/browse/PHOENIX-3556
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.5.2
Environment: MacOs, Phoenix 4.5.2-HBase-0.98, Guava 20.0
Reporter: Bo Gao
Priority: Critical
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:
java.lang.IllegalAccessError: tried to access method

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.
