Description

Druid adapter requires Guava version 14 or higher. With guava-13.0.1 compile fails as follows, due to the missing Maps.asMap method, which was added in 14.0:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project calcite-druid: Compilation failure
[ERROR] /home/jhyde/regress/calcite/druid/src/main/java/org/apache/calcite/adapter/druid/DruidSchema.java:[66,16] method asMap in class com.google.common.collect.Maps cannot be applied to given types;
[ERROR] required: java.util.SortedSet<K>,com.google.common.base.Function<? super K,V>
[ERROR] found: com.google.common.collect.ImmutableSet<java.lang.String>,com.google.common.cache.LoadingCache<java.lang.String,org.apache.calcite.schema.Table>
[ERROR] reason: cannot infer type-variable(s) K,V
[ERROR] (argument mismatch; com.google.common.collect.ImmutableSet<java.lang.String> cannot be converted to java.util.SortedSet<K>)

We were incorrect to state that Calcite release 1.8 works with "Guava versions 12.0.1 to 19.0"; it should state "Guava versions 14.0 to 19.0".

Calcite release 1.7 and earlier do not have this problem.
