Re: Hadoopn1.03 There is insufficient memory for the Java Runtime Environment to continue.
some details to this problem:

12/10/05 12:13:27 INFO mapred.JobClient:  map 0% reduce 0%
12/10/05 12:13:40 INFO mapred.JobClient: Task Id :
attempt_201210051158_0001_m_000002_0, Status : FAILED
java.lang.Throwable: Child Error
at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:271)
Caused by: java.io.IOException: Task process exit with nonzero status of 134.
at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:258)

attempt_201210051158_0001_m_000002_0: #
attempt_201210051158_0001_m_000002_0: # There is insufficient memory
for the Java Runtime Environment to continue.
attempt_201210051158_0001_m_000002_0: # pthread_getattr_np

in mapred-site.xml the following memory settings were set after a
couple trials to get rid of the problem this way:

<property>
<name>mapred.child.java.opts</name>
<value>-server -Xmx4096M -Djava.net.preferIPv4Stack=true</value>
</property>

<property>
<name>mapred.child.ulimit</name>
<value>16777216</value>
</property>

Cheers,
Attila
