I may be wrong, but all(?) examples I’ve seen with Apache Hadoop takes as input a file stored on the local file system (e.g. org.apache.hadoop.examples.Grep)
Is there a way to load and save the data on the Hadoop file system (HDFS)? For example I put a tab delimited file named ‘stored.xls’ on HDFS using hadoop-0.19.1/bin/hadoop dfs -put ~/local.xls stored.xls. How should I configure the JobConf to read it ?
Thanks .
JobConf conf = new JobConf(getConf(), ...); ... FileInputFormat.setInputPaths(conf, new Path('stored.xls')) ... JobClient.runJob(conf); ...setInputPaths will do it.
