| 107 | <P> |
---|
| 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 |
---|
