Namenode works fine, anyone has same experience before ?
Not sure. We install CDH4.7 (with Hadoop 2.0) and CDH 5.3.1 ( with Hadoop 2.5.0 ) on CentOS 6.5 and RHEL 6.
Everything is fine.
Is there any error message ?
I installed Hadoop 2.6 on Ubuntun with Oracle JDK 1.8, it works fine.
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)
