I'm writing into BigTable using JavaHBaseContext bulkput API. This is working fine with below spark and scala version
<spark.version>2.3.4</spark.version>
<scala.version>2.11.8</scala.version>
We just created a new dataproc cluster with Spark 2.4(1.5.23-debian10 image version) I upgraded the spark and scala dependencies to use below spark and scala version and started getting issue as listed below.
<spark.version>2.4.7</spark.version>
<scala.version>2.12.10</scala.version>

It seems to me that it is not able to instantiate the HBaseConnectionCache class because it is unable to found scala/Product$class But I have excluded the scala-library from everywhere and now its only coming from its own dependency. Any lead would be helpful.
