Could not initialize class com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystemConfiguration

[lvijnck]

I'm unable to setup the connector through maven according to the docs:

The following works, unfortunately it's slow as it re-downloads the jar every time.

spark.jars: https://storage.googleapis.com/hadoop-lib/gcs/gcs-connector-hadoop3-latest.jar
spark.hadoop.fs.gs.impl: com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem
spark.hadoop.fs.AbstractFileSystem.gs.impl: com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS

spark.hadoop.google.cloud.auth.service.account.enable: true
spark.hadoop.google.cloud.auth.service.account.json.keyfile: conf/local/service-account.json

Hence why we would like to maven, but we're unable to get that working

spark.jars.packages: com.google.cloud.bigdataoss:gcs-connector:hadoop3-2.2.19
spark.hadoop.fs.gs.impl: com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem
spark.hadoop.fs.AbstractFileSystem.gs.impl: com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS

spark.hadoop.google.cloud.auth.service.account.enable: true
spark.hadoop.google.cloud.auth.service.account.json.keyfile: conf/local/service-account.json

This gives the following error:

Shaded JAR from here works:

https://repo1.maven.org/maven2/com/google/cloud/bigdataoss/gcs-connector/hadoop3-2.0.0/

not sure how to get it from Maven though
