hadoop2.2的mapreduce问题

楼主，你的问题解决没？我现在用eclipse调用hadoop2.2，也出现异常，
- 2014-04-29 11:02:07,722  [main] org.apache.hadoop.mapreduce.Job.monitorAndPrintJob(1358) |Job job_1398738447901_0004 failed with state FAILED due to: Application application_1398738447901_0004 failed 2 times due to AM Container for appattempt_1398738447901_0004_000002 exited with  exitCode: 1 due to: Exception from container-launch:

有没有人知道是啥回事啊？
