Hello everybody. I'm executing a BFS algoritm on giraph, and i hit with this error. I searched for uppercase letters in the following files:
/etc/*hostname* /etc/*hosts* /usr/local/hadoop/zookeeper/conf/*zoo.cfg* (contains zookeeper configuration) /usr/local/hadoop/etc/hadoop/*masters* /usr/local/hadoop/etc/hadoop/*slaves* In my entire cluster (one master and two child nodes)*. *I couldn't find a single uppercase letter in those configurations files. My nodes have this names: *hdnode01* *hadoop100* *hadoop101* Is there any file left that i should check in order to detect where is my mistake? This problem can be related with any other configuration problem? Thanks Alessio for your contribution, you help me a lot writing this, and you could help me a lot more if you help me here !! :D Bye!
