I’ve trying to overcome sudden problem. Befor that problem I’ve used old VM. I’ve downloaded the new one VM and still can’t make my job run. I get Java heap space error.
I’ve alredy read this one post: out of Memory Error in Hadoop

Here is my configs from /etc/hadoop/conf:

sudo vi hadoop-env.sh

# Extra Java runtime options.  Empty by default.
#export HADOOP_OPTS="-Djava.net.preferIPv4Stack=true $HADOOP_CLIENT_OPTS"
export HADOOP_CLIENT_OPTS="-Xmx256m $HADOOP_CLIENT_OPTS"

Here is my mapred-site.xml

<property>
    <name>mapred.child.java.opts</name>
    <value>-Xmx256m</value>
  </property>
  <property>
    <name>io.sort.mb</name>
    <value>128</value>
  </property>

Nothing helps 🙁

Here is the console output:

Ok so seems like the problem is solved. Here is my mapred-site.xml

<configuration>
  <property>
    <name>mapred.job.tracker</name>
    <value>0.0.0.0:8021</value>
  </property>

  <property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
  </property>

  <property>
    <description>To set the value of tmp directory for map and reduce tasks.</description>
    <name>mapreduce.task.tmp.dir</name>
    <value>/var/lib/hadoop-mapreduce/cache/${user.name}/tasks</value>
  </property>

  <property>
    <name>jobtracker.thrift.address</name>
    <value>0.0.0.0:9290</value>
  </property>
  <property>
    <name>mapred.jobtracker.plugins</name>
    <value>org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin</value>
    <description>Comma-separated list of jobtracker plug-ins to be activated.</description>
  </property>
  <property>
      <name>mapred.child.java.opts</name>
      <value>-Xmx512m</value>
  </property>
  <property>
      <name>io.sort.mb</name>
      <value>64</value>
  </property>
</configuration>

Here is my hadoop-env.sh:

export HADOOP_CLIENT_OPTS="-Xmx512m -XX:-HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/home/cloudera/heapdump $HADOOP_CLIENT_OPTS"

I suppose the problem was in changes applying. Only restart helped me. I’ve tried to restart services – no effect.
