Steve Loughran commented on SPARK-799:
--------------------------------------
If you want to go into the JVM. then there's a .JS script interpreter built
into the JVM which can be called from the CLI.
However (and perhaps the scala script has the same problem), the JVM is the
wrong level to do things like setup env vars, classpaths, probe for native libs
being on PATH, etc.
Powershell is at the right layer in the code, it's just something which will
need its own set of windows tests to validate; maybe someone setting up a
Jenkins build somewhere (ASF Infra?) to nightly test them
> Windows versions of the deploy scripts

> Key: SPARK-799
> URL: https://issues.apache.org/jira/browse/SPARK-799
> Project: Spark
> Issue Type: Bug
> Components: Deploy, Windows
> Reporter: Matei Zaharia
> Labels: Starter
>
> Although the Spark daemons run fine on Windows with run.cmd, the deploy
> scripts (bin/start-all.sh and such) don't do so unless you have Cygwin. It
> would be nice to make .cmd versions of those.
