Spark 0.5.2 is a minor release, whose main addition is to allow Spark to compile against Hadoop 2 distributions. To do this, edit
project/SparkBuild.scala and change both the
HADOOP_MAJOR_VERSION variables, then recompile Spark. This change was contributed by Thomas Dudziak.
You can download Spark 0.5.2 as a tar.gz file (2 MB).
