----------------------------------
Summary: Treat Scala compiler warnings as errors
Key: SPARK-9262
URL: https://issues.apache.org/jira/browse/SPARK-9262
Project: Spark
Issue Type: Improvement
Components: Build
Reporter: Reynold Xin
Assignee: Reynold Xin
I've seen a few cases in the past few weeks that the compiler is throwing
warnings that are caused by legitimate bugs. This patch updates warnings to
errors, except deprecation warnings.
Note that ideally we should be able to mark deprecation warnings as errors as
well. However, due to the lack of ability to suppress individual warning
messages in the Scala compiler, we cannot do that (since we do need to access
deprecated APIs in Hadoop).
