> Prune obsolete classes in org.apache.hadoop.io.serializer
> ---------------------------------------------------------

>                 Key: HADOOP-19932
>                 URL: https://issues.apache.org/jira/browse/HADOOP-19932
>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: io
>    Affects Versions: 3.5.1, 3.6.0
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Minor
>              Labels: pull-request-available
>             Fix For: 3.5.1, 3.6.0
>
>
> There's a collection of classes in org.apache.hadoop.io.serializer which try 
> to bridge between Writable and Serializable.
> None of this code has been touched for a decade and may not be used; get rid 
> of the cruft.
> Although tagged LimitedPrivate MapReduce, it may get used downstream in 
> places like spark; which may notice if cut.
> so prune carefully.
