Sean Owen updated SPARK-17542:
------------------------------
    Issue Type: Improvement  (was: Bug)

There are unfortunately a number of warnings, and I don't think we want a JIRA for each of them. Somebody whacks a lot of them periodically. So, sure, they're good to resolve but I'd be more interested in sweeps that clean up as many warnings as possible. Some are un-suppressable and un-resolvable, like tests for deprecated methods in Scala. This isn't a bug though.

> When building Spark with Java 8, there is a compiler warning in the class UnsafeInMemorySorter:
> {noformat}
> [WARNING] .../core/src/main/java/org/apache/spark/util/collection/unsafe/sort/UnsafeInMemorySorter.java:284: warning: [static] 
> static method should be qualified by type name, TaskMemoryManager, instead of
>  by an expression
> {noformat}
> Spark should compile without these kinds of warnings.
