I think I now have everything living in
org.apache.spark.sql.datasketches
Some of the traits we extend use constructs like
Seq[AbstractDataType]
, which is fine except thatAbstractDataType
is declared asprivate[sql]
, meaning it's only visible to things inorg.apache.spark.sql
. We might be able to get away with usingSeq[DataType]
but that's a subtype of its abstract parent and not everything inherits from it. Similarly, the genericNumericType
is also not public.These seem like design flaws in Spark, IMHO, but I'm not going to try getting them to change that at this point.
