> Components: SQL
> Affects Versions: 2.1.0

> Priority: Minor
> Fix For: 2.1.1
>
>
> Currently, {{inferDataType(TypeToken)}} is called from a different maven
> module, and because we shade Guava, that sometimes leads to errors (e.g. when
> running tests using maven):
> {noformat}
> udf3Test(test.org.apache.spark.sql.JavaUDFSuite) Time elapsed: 0.084 sec
> <<< ERROR!
> java.lang.NoSuchMethodError:
> org.apache.spark.sql.catalyst.JavaTypeInference$.inferDataType(Lcom/google/common/reflect/TypeToken;)Lscala/Tuple2;
> at
> test.org.apache.spark.sql.JavaUDFSuite.udf3Test(JavaUDFSuite.java:107)
> Results :
> Tests in error:
> JavaUDFSuite.udf3Test:107 ยป NoSuchMethod
> org.apache.spark.sql.catalyst.JavaTyp...
> {noformat}
> Instead, we shouldn't expose Guava types in these APIs.
