示例1: doMapReduce

import org.apache.hadoop.hbase.mapreduce.JobUtil; //导入依赖的package包/类
/**
 * Execute compaction, using a Map-Reduce job.
 */
private int doMapReduce(final FileSystem fs, final Set<Path> toCompactDirs,
    final boolean compactOnce, final boolean major) throws Exception {
  Configuration conf = getConf();
  conf.setBoolean(CONF_COMPACT_ONCE, compactOnce);
  conf.setBoolean(CONF_COMPACT_MAJOR, major);

  Job job = new Job(conf);
  job.setJobName("CompactionTool");
  job.setJarByClass(CompactionTool.class);
  job.setMapperClass(CompactionMapper.class);
  job.setInputFormatClass(CompactionInputFormat.class);
  job.setOutputFormatClass(NullOutputFormat.class);
  job.setMapSpeculativeExecution(false);
  job.setNumReduceTasks(0);

  // add dependencies (including HBase ones)
  TableMapReduceUtil.addDependencyJars(job);

  Path stagingDir = JobUtil.getStagingDir(conf);
  try {
    // Create input file with the store dirs
    Path inputPath = new Path(stagingDir, "compact-"+ EnvironmentEdgeManager.currentTime());
    CompactionInputFormat.createInputFile(fs, inputPath, toCompactDirs);
    CompactionInputFormat.addInputPath(job, inputPath);

    // Initialize credential for secure cluster
    TableMapReduceUtil.initCredentials(job);

    // Start the MR Job and wait
    return job.waitForCompletion(true) ? 0 : 1;
  } finally {
    fs.delete(stagingDir, true);
  }
}
