Sean Owen commented on SPARK-20284:
-----------------------------------
It's a developer API, so dont' think callers will generally be using this.
try-with-resources isn't a JVM feature, it's a Java language feature. For
example this doesn't do anything for Scala AFAIK.
> Make SerializationStream and DeserializationStream extend Closeable
> -------------------------------------------------------------------
>
> Key: SPARK-20284
> URL: https://issues.apache.org/jira/browse/SPARK-20284
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.6.3, 2.1.0
> Reporter: Sergei Lebedev
> Priority: Trivial
>
> Both {{SerializationStream}} and {{DeserializationStream}} implement
> {{close}} but do not extend {{Closeable}}. As a result, these streams cannot
> be used in try-with-resources.
> Was this intentional or rather nobody ever needed that?
