The context bound changes won't work on the two public methods:
```
[error] * deprecated method
accumulableCollection(java.lang.Object,scala.Function1,scala.reflect.ClassTag)org.apache.spark.Accumulable
in class org.apache.spark.SparkContext's type is different in current version,
where it is
(java.lang.Object,scala.reflect.ClassTag,scala.Function1)org.apache.spark.Accumulable
instead of
(java.lang.Object,scala.Function1,scala.reflect.ClassTag)org.apache.spark.Accumulable
[error] filter with:
ProblemFilters.exclude[IncompatibleMethTypeProblem]("org.apache.spark.SparkContext.accumulableCollection")
[error] * method
this(org.apache.spark.rdd.RDD,java.lang.Class,java.lang.Class,scala.Function1,scala.reflect.ClassTag,scala.Function1,scala.reflect.ClassTag)Unit
in class org.apache.spark.rdd.SequenceFileRDDFunctions's type is different in
current version, where it is
(org.apache.spark.rdd.RDD,java.lang.Class,java.lang.Class,scala.reflect.ClassTag,scala.reflect.ClassTag,scala.Function1,scala.Function1)Unit
instead of
(org.apache.spark.rdd.RDD,java.lang.Class,java.lang.Class,scala.Function1,scala.reflect.ClassTag,scala.Function1,scala.reflect.ClassTag)Unit
[error] filter with:
ProblemFilters.exclude[IncompatibleMethTypeProblem]("org.apache.spark.rdd.SequenceFileRDDFunctions.this")
```
Quite unfortunately, they generate signatures that take the same arguments
but in differing orders. This bit is one of those tiny breaking changes that
will have to wait for Spark 3.x. As I recall they still work in Scala 2.12,
even though they are deprecated.
