Best way to create Mutliple files into a single RDD

val fileRDD = sc.textFile(filename).repartition(1)

Where the filename is the location of your directory only.

Setting up Flume NG, listening to syslog over UDP, with an S3 Sink

My goal was to set up Flume on my web instances, and write all events into s3, so I could easily use other tools like Amazon Elastic Map Reduce, and Amazon Red Shift.

I didn't want to have to deal with log rotation myself, so I setup Flume to read from a syslog UDP source. In this case, Flume NG acts as a syslog server, so as long as Flume is running, my web application can simply write to it in syslog format on the specified port. Most languages have plugins for this.

At the time of this writing, I've been able to get Flume NG up and running on 3 ec2 instances, and all writing to the same bucket.

Install Flume NG on instances

	// CREATE COLLECTION
	solr create_collection -c my_collection -shards 2 -d path-to-my-conf

	// CHECK COLLECTION SCHEMA
	curl http://solr-host.dev:8983/solr/my_collection/schema?wt=schema.xml
	// SCHEMA ITS GOOD



	// UPDATE SCHEMA
