Sean Owen commented on SPARK-10074:
-----------------------------------
Yes, and it generates more code. I would argue against this until there's a use
for it.
> Include Float in @specialized annotation

> Key: SPARK-10074
> URL: https://issues.apache.org/jira/browse/SPARK-10074
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Ted Yu
> Priority: Minor
>
> There're several places in Spark codebase where we use @specialized
> annotation covering Long and Double.
> e.g. in OpenHashMap.scala :
> {code}
> class OpenHashMap[K : ClassTag, @specialized(Long, Int, Double) V: ClassTag](
> initialCapacity: Int)
> {code}
> Float should be added to @specialized annotation as well.
