How to setup a hadoop node to be a tasktracker but not a datanode?

You have to setup a host-exclude file for your namenode. This edit in the core-site.xml.

You have to setup a host-exclude file for your namenode. This edit in the core-site. Xml: dfs.hosts.

Exclude YOUR_PATH_TO_THE_EXCLUDE_FILE This file is basically like a slave or master file. You have to just insert the hostname like: host1 host2 When restarting the namenode will ignore these given hosts but the jobtracker will launch a tasktracker.

Thanks for your answer. I did exactly what you said, but the datanode is still running in the excluded node. Do I need a special name for the exclude file.

I have "exclude_dfs_hosts" and put in core-site. Xml this ' YOUR_PATH_TO_THE_EXCLUDE_FILE\exclude_dfs_hosts' – lcb Jun 1 at 17:50 Wierd, it is working now, wasn't in the first time. Thanks a lot.

Some one should update the configuration manual :) – lcb Jun 1 at 17:58 actually you have to replace the path that I wrote in capslock with your path. The file should be readable to the user which starts hadoop. But if it works now :) Fine!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
