avro.shaded not in fatJar causing java.lang.NoClassDefFoundError

[rnonnon]

Hi,

I'm using spark-bigquery-with-dependencies 0.20.0 and facing a

 java.lang.NoClassDefFoundError: com/google/cloud/spark/bigquery/repackaged/avro/shaded/com/google/common/base/Preconditions

When calling com.google.cloud.spark.bigquery.SchemaConverters#toBigQuerySchema

It seems this class does an import on avro.shaded.com.google.common.base.Preconditions
But avro.shaded is not included into the FatJar.

If my searches are fine :
org.apache.avro comes with hadoop-common itselft coming with beam-sdks-java-io-hadoop-common but as a provided dependency. This is the reason why it's not embedded into the fatJar.

To fix the issue I argue to replace com.google.cloud.spark.bigquery.SchemaConverters:18
import avro.shaded.com.google.common.base.Preconditions;
with
import com.google.common.base.Preconditions;

Thanks ;)
