+Vargrant provisioning files to spin up a modest Spark cluster (master
++ 3 slaves + backup) for experiments processing HTRC Extracted Feature
+JSON files suitable for ingesting into Solr.
+
+To aid parallelism, code is designed to read JSON files from HDFS, so
+the provision of the cluster includes Hadoop core in addition to Spark
 
 
-Top-level code Apache Spark, processing HDFS stored JSON files, hence
-the need for an underlying Hadoop cluster.
+Provisioning uses Puppet scripting, based on the following on-line
+resources, but updated to use newer versions of Ubuntu, Java,
+and Hadoop.  Spark is then added in on top of that.

+
+To get everything setup, type:
+
+  vargrant up
+
+Then log in to the master node, and swithc to 'ubuntu' user
+
+  vargrant ssh master
+  sudo su - ubuntu
+
+If the first time, you need to format an HDFS area to use:
+  hdfs namenode -format
+
+Otherwise start up HDFS and Spark deamon processes:
+
+  start-dfs.sh
+  spark-start-all.sh
