git commit: SPARK-1167: Remove metrics-ganglia from default build due
to LGPL issues...
Repository: spark
Updated Branches:
refs/heads/master 2a2c9645e -> 16788a654
SPARK-1167: Remove metrics-ganglia from default build due to LGPL issues...
This patch removes Ganglia integration from the default build. It
allows users willing to link against LGPL code to use Ganglia
by adding build flags or linking against a new Spark artifact called
spark-ganglia-lgpl.
This brings Spark in line with the Apache policy on LGPL code
enumerated here:
https://www.apache.org/legal/3party.html#options-optional
Author: Patrick Wendell <pw...@gmail.com>
Closes #108 from pwendell/ganglia and squashes the following commits:

+
+To install the `GangliaSink` you'll need to perform a custom build of Spark. _**Note that
+by embedding this library you will include [LGPL](http://www.gnu.org/copyleft/lesser.html)-licensed
+code in your Spark package**_. For sbt users, set the
+`SPARK_GANGLIA_LGPL` environment variable before building. For Maven users, enable
+the `-Pspark-ganglia-lgpl` profile. In addition to modifying the cluster's Spark build
+user applications will need to link to the `spark-ganglia-lgpl` artifact.

The syntax of the metrics configuration file is defined in an example configuration file,
`$SPARK_HOME/conf/metrics.properties.template`.
