Hello, I have a Hadoop/Hbase cluster, cloudera cdh3u0 version, with several machines. I've created a job that does some work using the information from a HBase table.
The next example *works* fine: - start JobTracker - start TaskTracker *on the same machine* as the JobTracker - run the job - the job completes successfully The next example *does not work*: - start JobTracker - start TaskTracker *on another machine* (not the same as the JobTracker) - run the job - I get the next error in the console: 11/04/21 12:21:01 INFO mapred.JobClient: Running job: job_201104201820_0007 11/04/21 12:21:02 INFO mapred.JobClient: map 0% reduce 0% 11/04/21 12:21:02 INFO mapred.JobClient: Task Id : attempt_201104201820_0007_m_000002_0, Status : FAILED Error initializing attempt_201104201820_0007_m_000002_0: java.io.FileNotFoundException: File file:/var/ui/hadoop/mapred/system/job_201104201820_0007/jobToken<file:///var/ui/hadoop/mapred/system/job_201104201820_0007/jobToken>does not exist. at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:383) at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:251) at org.apache.hadoop.mapred.TaskTracker.localizeJobTokenFile(TaskTracker.java:4033) at org.apache.hadoop.mapred.TaskTracker.initializeJob(TaskTracker.java:1148) at org.apache.hadoop.mapred.TaskTracker.localizeJob(TaskTracker.java:1089) at org.apache.hadoop.mapred.TaskTracker.startNewTask(TaskTracker.java:2257) at org.apache.hadoop.mapred.TaskTracker$TaskLauncher.run(TaskTracker.java:2221) 11/04/21 12:21:02 WARN mapred.JobClient: Error reading task outputhttp:// cene.ro.schlund.net:50060/tasklog?plaintext=true&attemptid=attempt_201104201820_0007_m_000002_0&filter=stdout 11/04/21 12:21:02 WARN mapred.JobClient: Error reading task outputhttp:// cene.ro.schlund.net:50060/tasklog?plaintext=true&attemptid=attempt_201104201820_0007_m_000002_0&filter=stderr 11/04/21 12:21:02 INFO mapred.JobClient: Task Id : attempt_201104201820_0007_r_000002_0, Status : FAILED Can you help me with this problem?
