I have installed Hadoop-2.4.0 on sigle node cluster. After starting the dfs and yarn and executing the jps I get the following services running..

6584 ResourceManager
5976 NameNode
6706 NodeManager
6407 SecondaryNameNode
6148 DataNode
7471 Jps

When I try to execute the following command I get the error

hduser@dhruv-VirtualBox:/usr/local/hadoop$ bin/hdfs dfs -mkdir /hello

OpenJDK 64-Bit Server VMwarning: You have loaded llibrary /usr/local/hadoop-2.4.0/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now. It's highly recommended that you fix the library with 'execstack' -c ', or link it with '-z noexecstack. 14/10/22 12:21:36 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin java classes where applicable.

Can please somebody suggest me, what is wrong and how to rectify this ?

Thanks Dhruv

You can ignore that if you want. It means that you are running a 32-bit native libraries on a 64-bit runtime.
If the log still annoys you, then you need to build those native libraries on a 64-bit environment.
