Thanks sonja for your answer. I check *core-site.xml* and *mapred-site.xml* on all nodes of the cluster. Also* yarn-site.xml* and *$HOME/.ssh/authorized_keys*.
I looked for hdnode01, hadoop100 and hadoop101 using grep like this: *sudo grep -Riol "hadoop101" $HADOOP_HOME* I also search in $GIRAPH_HOME. I couldn't find any letter in uppercase. *grep -io* lets us search without giving attention to upper or lowercase letters, just search the value. I used it for searching if i have some uppercase letters for those values. I'm starting to believe that must be related, maybe, with something else. Anyway, help is always welcome!! :D Bye! 2015-08-11 5:38 GMT-03:00 Sonja Koenig <[email protected]>: > Hi there! > > Have you checked your hadoop config files ($HADOOP_HOME/conf)? > especially $HADOOP_HOME/conf/*core-site.xml* > and $HADOOP_HOME/conf/*mapred-site.xml* > > And you might also want to check in your ~/*.ssh/config* - if you have > one. > > Hope that helps :) > Sonja > > > > Am 11.08.2015 um 03:46 schrieb José Luis Larroque: > > Hello everybody.
