[jira] [Updated] (SPARK-10074) Include Float in @specialized annotation

["Sean Owen (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-10074?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated SPARK-10074:
------------------------------
    Component/s: Spark Core

Where would this get used though? I didn't see any usages of floats in these maps. It's not worth it unless the code would take advantage of them.

> 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.
