Hi folks,
I've just done a fresh install of Hadoop, Namenode and datanode are up,
Task/job Tracker also up, but when I run the Map reduce worcount exemple I got
this error on Task tracker:
2011-12-23 15:11:52,679 INFO org.apache.hadoop.mapred.JvmManager: JVM :
jvm_201112231511_0001_m_-1653678851 exited with exit code 134. Number of tasks
it ran: 0
2011-12-23 15:11:52,681 WARN org.apache.hadoop.mapred.TaskRunner:

java.io.IOException: Task process exit with nonzero status of 134.
at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258)
And job tracker stuck :
# hadoop jar hadoop-examples*.jar wordcount input/test.txt output/
11/12/23 15:11:48 INFO input.FileInputFormat: Total input paths to process : 1

11/12/23 15:11:50 INFO mapred.JobClient: map 0% reduce 0%
I'running hadoop 0.20.203.0, java 1.6.0 rev 25
I've done some googling, apparently the JVM crash hard (maybe Out of memory),
does someone have any hint ?
