Java snippet for Configuraion
{quote}configuration.set("fs.default.name", "hdfs://localhost:9000");
configuration.set("mapred.job.tracker", "hdfs://localhost:9000");{quote}
I'm using a single datanode to read the files that where written to hdfs by
flume, my java program just reads the files from hdfs to show it on the screen
nothing much.
