111	A map/reduce job configuration.
112
113	<p><code>JobConf</code> is the primary interface for a user to describe a
114	map-reduce job to the Hadoop framework for execution. The framework tries to
115	faithfully execute the job as-is described by <code>JobConf</code>, however:
116	<ol>
117	<li>
118	Some configuration parameters might have been marked as
119	<a href="../../../../org/apache/hadoop/conf/Configuration.html#FinalParams">
120	final</a> by administrators and hence cannot be altered.
121	</li>
122	<li>
123	While some job parameters are straight-forward to set
124	(e.g. <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setNumReduceTasks(int)"><CODE>setNumReduceTasks(int)</CODE></A>), some parameters interact subtly
125	rest of the framework and/or job-configuration and is relatively more
126	complex for the user to control finely (e.g. <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setNumMapTasks(int)"><CODE>setNumMapTasks(int)</CODE></A>).
127	</li>
128	</ol></p>
129
130	<p><code>JobConf</code> typically specifies the <A HREF="../../../../org/apache/hadoop/mapred/Mapper.html" title="interface in org.apache.hadoop.mapred"><CODE>Mapper</CODE></A>, combiner
131	(if any), <A HREF="../../../../org/apache/hadoop/mapred/Partitioner.html" title="interface in org.apache.hadoop.mapred"><CODE>Partitioner</CODE></A>, <A HREF="../../../../org/apache/hadoop/mapred/Reducer.html" title="interface in org.apache.hadoop.mapred"><CODE>Reducer</CODE></A>, <A HREF="../../../../org/apache/hadoop/mapred/InputFormat.html" title="interface in org.apache.hadoop.mapred"><CODE>InputFormat</CODE></A> and
132	<A HREF="../../../../org/apache/hadoop/mapred/OutputFormat.html" title="interface in org.apache.hadoop.mapred"><CODE>OutputFormat</CODE></A> implementations to be used etc.
133
134	<p>Optionally <code>JobConf</code> is used to specify other advanced facets
135	of the job such as <code>Comparator</code>s to be used, files to be put in
136	the <A HREF="../../../../org/apache/hadoop/filecache/DistributedCache.html" title="class in org.apache.hadoop.filecache"><CODE>DistributedCache</CODE></A>, whether or not intermediate and/or job outputs
137	are to be compressed (and how), debugability via user-provided scripts
138	( <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setMapDebugScript(java.lang.String)"><CODE>setMapDebugScript(String)</CODE></A>/<A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setReduceDebugScript(java.lang.String)"><CODE>setReduceDebugScript(String)</CODE></A>),
139	for doing post-processing on task logs, task's stdout, stderr, syslog.
140	and etc.</p>
141
142	<p>Here is an example on how to configure a job via <code>JobConf</code>:</p>
143	<p><blockquote><pre>
144	// Create a new JobConf
145	JobConf job = new JobConf(new Configuration(), MyJob.class);
146
147	// Specify various job-specific parameters
148	job.setJobName("myjob");
149
150	FileInputFormat.setInputPaths(job, new Path("in"));
151	FileOutputFormat.setOutputPath(job, new Path("out"));
152
153	job.setMapperClass(MyJob.MyMapper.class);
154	job.setCombinerClass(MyJob.MyReducer.class);
155	job.setReducerClass(MyJob.MyReducer.class);
156
157	job.setInputFormat(SequenceFileInputFormat.class);
158	job.setOutputFormat(SequenceFileOutputFormat.class);

2393	<p><i>Note</i>: This is only a <i>hint</i> to the framework. The actual

2395	generated by the job's <A HREF="../../../../org/apache/hadoop/mapred/InputFormat.html#getSplits(org.apache.hadoop.mapred.JobConf, int)"><CODE>InputFormat.getSplits(JobConf, int)</CODE></A>.
2396
2397	A custom <A HREF="../../../../org/apache/hadoop/mapred/InputFormat.html" title="interface in org.apache.hadoop.mapred"><CODE>InputFormat</CODE></A> is typically used to accurately control
2398	the number of map tasks for the job.</p>
2399
2400	<h4 id="NoOfMaps">How many maps?</h4>
2401
2402	<p>The number of maps is usually driven by the total size of the inputs
2403	i.e. total number of blocks of the input files.</p>
2404
2405	<p>The right level of parallelism for maps seems to be around 10-100 maps
2406	per-node, although it has been set up to 300 or so for very cpu-light map
2407	tasks. Task setup takes awhile, so it is best if the maps take at least a
2408	minute to execute.</p>
2409
2410	<p>The default behavior of file-based <A HREF="../../../../org/apache/hadoop/mapred/InputFormat.html" title="interface in org.apache.hadoop.mapred"><CODE>InputFormat</CODE></A>s is to split the
2411	input into <i>logical</i> <A HREF="../../../../org/apache/hadoop/mapred/InputSplit.html" title="interface in org.apache.hadoop.mapred"><CODE>InputSplit</CODE></A>s based on the total size, in
2412	bytes, of input files. However, the <A HREF="../../../../org/apache/hadoop/fs/FileSystem.html" title="class in org.apache.hadoop.fs"><CODE>FileSystem</CODE></A> blocksize of the
2413	input files is treated as an upper bound for input splits. A lower bound
2414	on the split size can be set via
2415	<a href="../../../../../mapred-default.html#mapred.min.split.size">
2416	mapred.min.split.size</a>.</p>
2417
2418	<p>Thus, if you expect 10TB of input data and have a blocksize of 128MB,
2419	you'll end up with 82,000 maps, unless <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setNumMapTasks(int)"><CODE>setNumMapTasks(int)</CODE></A> is
