From 8c5a2226932c572898c76eb6fab9283f02ad4103 Mon Sep 17 00:00:00 2001 From: Hari Shreedharan Date: Wed, 20 Aug 2014 04:09:54 -0700 Subject: [SPARK-3054][STREAMING] Add unit tests for Spark Sink. This patch adds unit tests for Spark Sink. It also removes the private[flume] for Spark Sink, since the sink is instantiated from Flume configuration (looks like this is ignored by reflection which is used by Flume, but we should still remove it anyway).
