Alexander Ulanov commented on SPARK-6673:
-----------------------------------------
Probably similar issue: I am trying to execute unit tests in MLlib with
LocalClusterSparkContext on Windows 7. I am getting a bunch of error in the log
saying that: "Cannot find any assembly build directories." If I do set
SPARK_SCALA_VERSION=2.10 then I get "No assemblies found in
'C:\dev\spark\mllib\.\assembly\target\scala-2.10'"
> spark-shell.cmd can't start even when spark was built in Windows

> Failed to find Spark assembly JAR.
> You need to build Spark before running this program.
> {code}
> even when we have built spark.
> This is because of the lack of the environment {{SPARK_SCALA_VERSION}} which
> is used in {{spark-class2.cmd}}.
> In linux scripts, this value is set as {{2.10}} or {{2.11}} by default in
> {{load-spark-env.sh}}, but there are no equivalent script in Windows.
> As workaround, by executing
> {code}
> set SPARK_SCALA_VERSION=2.10
> {code}
> before execute spark-shell.cmd, we can successfully start it.
