108<code>JobClient</code> is the primary interface for the user-job to interact
109 with the <A HREF="../../../../org/apache/hadoop/mapred/JobTracker.html" title="class in org.apache.hadoop.mapred"><CODE>JobTracker</CODE></A>.
110 
111 <code>JobClient</code> provides facilities to submit jobs, track their
112 progress, access component-tasks' reports/logs, get the Map-Reduce cluster
113 status information etc.
114 
115 <p>The job submission process involves:
116 <ol>
117   <li>
118   Checking the input and output specifications of the job.
119   </li>
120   <li>
121   Computing the <A HREF="../../../../org/apache/hadoop/mapred/InputSplit.html" title="interface in org.apache.hadoop.mapred"><CODE>InputSplit</CODE></A>s for the job.
122   </li>
123   <li>
124   Setup the requisite accounting information for the <A HREF="../../../../org/apache/hadoop/filecache/DistributedCache.html" title="class in org.apache.hadoop.filecache"><CODE>DistributedCache</CODE></A> 
125   of the job, if necessary.
126   </li>
127   <li>
128   Copying the job's jar and configuration to the map-reduce system directory
129   on the distributed file-system.
130   </li>
131   <li>
132   Submitting the job to the <code>JobTracker</code> and optionally monitoring
133   it's status.
134   </li>
135 </ol></p>
136 
137 Normally the user creates the application, describes various facets of the
138 job via <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html" title="class in org.apache.hadoop.mapred"><CODE>JobConf</CODE></A> and then uses the <code>JobClient</code> to submit
139 the job and monitor its progress.
140 
141 <p>Here is an example on how to use <code>JobClient</code>:</p>
142 <p><blockquote><pre>
143     // Create a new JobConf
144     JobConf job = new JobConf(new Configuration(), MyJob.class);
145     
146     // Specify various job-specific parameters     
147     job.setJobName("myjob");
148     
149     job.setInputPath(new Path("in"));
150     job.setOutputPath(new Path("out"));
151     
152     job.setMapperClass(MyJob.MyMapper.class);
153     job.setReducerClass(MyJob.MyReducer.class);
154
155     // Submit the job, then poll for progress until the job is complete
156     JobClient.runJob(job);
157 </pre></blockquote></p>
158 
159 <h4 id="JobControl">Job Control</h4>
160 
161 <p>At times clients would chain map-reduce jobs to accomplish complex tasks
162 which cannot be done via a single map-reduce job. This is fairly easy since
163 the output of the job, typically, goes to distributed file-system and that
164 can be used as the input for the next job.</p>
165 
166 <p>However, this also means that the onus on ensuring jobs are complete
167 (success/failure) lies squarely on the clients. In such situations the
168 various job-control options are:
169 <ol>
170   <li>
171   <A HREF="../../../../org/apache/hadoop/mapred/JobClient.html#runJob(org.apache.hadoop.mapred.JobConf)"><CODE>runJob(JobConf)</CODE></A> : submits the job and returns only after
172   the job has completed.
173   </li>
174   <li>
175   <A HREF="../../../../org/apache/hadoop/mapred/JobClient.html#submitJob(org.apache.hadoop.mapred.JobConf)"><CODE>submitJob(JobConf)</CODE></A> : only submits the job, then poll the
176   returned handle to the <A HREF="../../../../org/apache/hadoop/mapred/RunningJob.html" title="interface in org.apache.hadoop.mapred"><CODE>RunningJob</CODE></A> to query status and make
177   scheduling decisions.
178   </li>
179   <li>
180   <A HREF="../../../../org/apache/hadoop/mapred/JobConf.html#setJobEndNotificationURI(java.lang.String)"><CODE>JobConf.setJobEndNotificationURI(String)</CODE></A> : setup a notification
181   on job-completion, thus avoiding polling.
182   </li>
183 </ol></p>
