After installing hadoop 2.2 and trying to launch pipes example ive got the folowing error (the same error shows up after trying to launch hadoop jar hadoop-mapreduce-examples-2.2.0.jar wordcount someFile.txt /out):

/usr/local/hadoop$ hadoop pipes -Dhadoop.pipes.java.recordreader=true -Dhadoop.pipes.java.recordwriter=true -input someFile.txt -output /out -program bin/wordcount

Instead use the mapred command for it.

Ive figured out that my IPv6 is disabled as it should be. Maybe my /etc/hosts are not correct?

/etc/hosts:

fe00::0         ip6-localnet
ff00::0         ip6-mcastprefix
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters

The problem connecting recource manager was because ive needed to add a few properties to yarn-site.xml :

<property>
<name>yarn.resourcemanager.address</name>
<value>127.0.0.1:8032</value>
</property>
<property>
<name>yarn.resourcemanager.scheduler.address</name>
<value>127.0.0.1:8030</value>
</property>
<property>
<name>yarn.resourcemanager.resource-tracker.address</name>
<value>127.0.0.1:8031</value>
</property>

Yet, my Jobs arent runing but connecting is successful now
