Bringing a node online
Hi,
I am running a 6 node, nutch 0.8. One of the node
goes down frequently (hardware problems). If the node
goes down the task tracker substitutes it and all is
well in the cluster.
When I try to bring the node online, the
currently executing job fails.
question: How do I safely bring node back online?
Thanks

Jay

Jay,
Have you tried simply running the tasktracker (plus the datanode if you
usually do run a datanode there)?
Something like
$HADOOP_HOME/bin/hadoop tasktracker
$HADOOP_HOME/bin/hadoop datanode
