------------------------------------
Summary: Fix code style and improve volatile for Spillable
Key: SPARK-15246
URL: https://issues.apache.org/jira/browse/SPARK-15246
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.0.0
Reporter: Lianhui Wang
for SPARK-4452
1. Fix code style
2. remote volatile of elementsRead method because there is only one thread to
use it.
3. avoid volatile of _elementsRead because Collection increases number of
_elementsRead when it insert a element. It is very expensive. So we can avoid
it.
