+# Spark-IPython-32bit
+
+Setup a Vagrant single node with Spark, IPython, and matplotlib, in a ubuntu/trusty32 VM
+
+### Content
+
+Vagrantfile
+apache-mirror-selector.py - Script to help select a Apache mirror to download from  
+ipython-pyspark.py - IPython notebook config and launch script  
+provision_spark_node.sh - Vagrant provisioning script  
+
+### Prereq
+
+Vagrant http://docs.vagrantup.com/v2/installation/index.html  
+VirtualBox https://www.virtualbox.org/wiki/Downloads as a provider  
+
+### Preparation
+
+  - Go to local directory and run `vagrant up`
+  - Vagrant will then prepare the VM - this should take about ~2 min to download the core vm (aka "box") and then ~4 min for other downloads and provisioning - it will require Internet connection to download various content from sources
+  - Spark distribution is automatically downloaded during the provisioning phase
+  - IPython notebook is downloaded and configured during provisioning, and it is launched with PySpark as the very last step
+  - To connect to IPython notebook, use http://localhost:1088. To see [SparkContext web UI](https://spark.apache.org/docs/latest/monitoring.html) use http://localhost:4040. Port forwarding is configured in Vagrant.
+  - If needed, use `vagrant ssh` to connect to the VM machine
+
+### Start/Stop
+
+#### IPython
+
+`vagrant ssh`
+
+stop: Ctrl-C to break  
+start:  
+`$ sudo su -`  
+`$ ./ipython-pyspark.py`
+
+Connect to [http://localhost:1088](http://localhost:1088)
+
+#### Spark
+
+Connect to [http://localhost:4040](http://localhost:4040) for the Spark UI (Driver)
+
+### Data transfer
+
+Vagrant support a "mapped directory". The local directory on the host where Vagrantfile is, is mapped to `/vagrant` in the VM. Any file there can be accessed from within the VM (use `vagrant ssh` to connect)
