From f2cfafdfe0f4b18f31bc63969e2abced1a66e896 Mon Sep 17 00:00:00 2001 From: Josh Rosen Date: Thu, 25 Feb 2016 17:04:43 -0800 Subject: [SPARK-13501] Remove use of Guava Stopwatch Our nightly doc snapshot builds are failing due to some issue involving the Guava Stopwatch constructor: ``` [error] /home/jenkins/workspace/spark-master-docs/spark/core/src/main/scala/org/apache/spark/scheduler/cluster/mesos/CoarseMesosSchedulerBackend.scala:496: constructor Stopwatch in class Stopwatch cannot be accessed in class CoarseMesosSchedulerBackend [error] val stopwatch = new Stopwatch() [error] ^ ``` This Stopwatch constructor was deprecated in newer versions of Guava (https://github.com/google/guava/commit/fd0cbc2c5c90e85fb22c8e86ea19630032090943) and it's possible that some classpath issues affecting Unidoc could be causing this to trigger compilation failures. In order to work around this issue, this patch removes this use of Stopwatch since we don't use it anywhere else in the Spark codebase.
