I am developing one project in hadoop using java. When i run my code(jar) on local cluster its working fine but when i run its on amazon multi cluster then it will give exception...
my code for mapreduce job....
job.setJarByClass(ReadActivityDriver.class);
job.setMapperClass(ReadActivityLogMapper.class);
job.setReducerClass(ReadActivityLogReducer.class);
job.setMapOutputKeyClass(Text.class);
job.setMapOutputValueClass(Text.class);
job.setInputFormatClass(ColumnFamilyInputFormat.class);
job.setOutputFormatClass(TextOutputFormat.class);
job.setOutputKeyClass(Text.class);
job.setOutputValueClass(Text.class);
ConfigHelper.setInputRpcPort(job.getConfiguration(), pro.getProperty("port"));
ConfigHelper.setInputInitialAddress(job.getConfiguration(), pro.getProperty("server"));
ConfigHelper.setInputPartitioner(job.getConfiguration(), "org.apache.cassandra.dht.Murmur3Partitioner");
ConfigHelper.setInputColumnFamily(job.getConfiguration(), keyspace, columnFamily);
SlicePredicate predicate = new SlicePredicate().setColumn_names(cn);
ConfigHelper.setInputSlicePredicate(job.getConfiguration(), predicate);
FileSystem.get(job.getConfiguration()).delete(new Path("ReadOutput"), true);
FileOutputFormat.setOutputPath(job, new Path("ReadOutput"));
job.waitForCompletion(true);
Exception which i am getting...
