问题
I'm trying to test the Spark-HBase connector in the GCP context and tried to follow the instructions, which asks to locally package the connector, and I get the following error when submitting the job on Dataproc (after having completed these steps).
Command
(base) gcloud dataproc jobs submit spark --cluster $SPARK_CLUSTER --class com.example.bigtable.spark.shc.BigtableSource --jars target/scala-2.11/cloud-bigtable-dataproc-spark-shc-assembly-0.1.jar --region us-east1 -- $BIGTABLE_TABLE
Error
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration

I found a working way, by adding following dependencies in build.sbt - thanks @jccampanero for the guidance !
libraryDependencies += "org.apache.hbase" % "hbase-common" % "2.0.2"
libraryDependencies += "org.apache.hbase" % "hbase-mapreduce" % "2.0.2"
Output (Bigtablesource.scala)
