Sean Owen commented on SPARK-5475:
----------------------------------
Eh, wait a sec, those tests are for testing Java 8 lambda support in Spark,
which isn't at all redundant. They compile and run fine. Are you using Java 8?
and setting {{-Pjava8-tests}?
> Java 8 tests are like maintenance overhead.

> Key: SPARK-5475
> URL: https://issues.apache.org/jira/browse/SPARK-5475
> Project: Spark
> Issue Type: Bug
> Reporter: Prashant Sharma
>
> Having tests that validate the same code compatible with java 8 and java 7 is
> like asserting that java 8 is backward compatible with java 7 and still
> supports java 8 features(lambda expressions to be precise). This was once
> necessary as asm was not compatible with java 8 and so on.
> Running java8-tests on the current code base results in more than 100
> compilation errors, it felt as if they are never run. This is based on the
> fact that compilation errors have existed for a pretty long period. So IMHO,
> we should really remove them, if we don't plan to maintain.
> Thoughts?
