No special error message, just when I run start-dfs.sh, when It goes to start DataNode, the script doesnt even ask me for SSH password ( it asked SSH password for NameNode and SecondNamenade) bash-4.1$ jps 6705 SecondaryNameNode 6298 NameNode 7487 Jps |

Also I tried Hadoop 2.7 with Oracle JDK 1.8 on on Redhat 6.5 today, same issue, maybe its related to the OS ? |

Got this error always, while people told me we can ignore it, its due to 32bit hadoop on 64bit OS 15/10/25 23:18:36 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable |
