Dear Wiki user, You have subscribed to a wiki page or wiki category on "Nutch Wiki" for change notification.
The following page has been changed by DennisKubes: http://wiki.apache.org/nutch/NutchHadoopTutorial ------------------------------------------------------------------------------ export HADOOP_SLAVES=${HADOOP_HOME}/conf/slaves }}} - There are other variables in this file which will affect the behavior of Hadoop. If when you start running the script later you start getting ssh errors, try changing the HADOOP_SSH_OPTS variable. Note also that, after the initial copy, you can set NUTCH_MASTER in your conf/hadoop-env.sh and it will use rsync to update the code running on each slave when you start daemons on that slave. + There are other variables in this file which will affect the behavior of Hadoop. If when you start running the script later you start getting ssh errors, try changing the HADOOP_SSH_OPTS variable. Note also that, after the initial copy, you can set HADOOP_MASTER in your conf/hadoop-env.sh and it will use rsync changes on the master to each slave node. There is a section below on how to do this. Next we are going to create the keys on the master node and copy them over to each of the slave nodes. This must be done as the nutch user we created earlier. Don't just su in as the nutch user, start up a new shell and login as the nutch user. If you su in the password-less login we are about to setup will not work in testing but will work when a new session is started as the nutch user.
