Lucene的IndexWriter初始化时的LockObtainFailedException的解决方法
1.先去hadoop官网下载hadoop的源码 http://svn.apache.org/repos/asf/hadoop/common/trunk
2.下载maven3，当前hadoop的最新版必须使用maven3编译
3.到hadoop下载源码目录执行mvn clean install；mvn eclipse:eclipse；
4.将源码导入eclipse；
5.在eclipse设置执行的WordCount.java的jvm启动参数，最少需要两个，输入目录和输出目录
6.然后就可以设置断点进行调试了，我们在处理mapreduce的主干流程上设置断点
org.apache.hadoop.mapred.LocalJobRunner这个类的run方法上
我们看到在我们设置的输入输出目录，然后使用默认的hadoop单机配置下，mapTask有16个，reduceTask有1个
我们先看看我们的输入目录，刚好是16个文件，说明每个输入文件默认启动一个mapTask
而reduce怎么是一个，怎么处理16个mapTask的输出呢
在org.apache.hadoop.mapred.ReduceTask这个reduce处理中run方法中会对所有的map输出做一个merge，然后作为reduceTask的输入
if (!isLocal) {
Class combinerClass = conf.getCombinerClass();
CombineOutputCollector combineCollector =
(null != combinerClass) ?
new CombineOutputCollector(reduceCombineOutputCounter, reporter, conf) : null;
Shuffle shuffle =
new Shuffle(getTaskID(), job, FileSystem.getLocal(job), umbilical,
super.lDirAlloc, reporter, codec,
combinerClass, combineCollector,
spilledRecordsCounter, reduceCombineInputCounter,
shuffledMapsCounter,
reduceShuffleBytes, failedShuffleCounter,
mergedMapOutputsCounter,
taskStatus, copyPhase, sortPhase, this,
mapOutputFile);
rIter = shuffle.run();
} else {
// local job runner doesn't have a copy phase
copyPhase.complete();
final FileSystem rfs = FileSystem.getLocal(job).getRaw();
rIter = Merger.merge(job, rfs, job.getMapOutputKeyClass(),
job.getMapOutputValueClass(), codec,
getMapFiles(rfs, true),
!conf.getKeepFailedTaskFiles(),
job.getInt(JobContext.IO_SORT_FACTOR, 100),
new Path(getTaskID().toString()),
job.getOutputKeyComparator(),
reporter, spilledRecordsCounter, null, null);
}
由于用到的是单机模式，所以没有用到Shuffle的过程。
整个日志输出如下：
