Hi all, I've tried to make a rack topology script. I've written it in python and it works if I call it with the following arguments: 10.2.0.1 10.2.0.11 10.2.0.11 10.2.0.12 10.2.0.21 10.2.0.26 10.2.0.31 10.2.0.33
The output is: /rack0 /rack1 /rack1 /rack1 /rack2 /rack2 /rack3 /rack3 Should the output be on newlines or is any whitespace sufficient? Additionally, my cluster's datanodes have DNS names such as: r1dn02 r2dn05 etc... I restarted the namenode in my running cluster (after configuring the topology script setting in core-site.xml). I ran a job and checked what the job tracker thinks the rack id's are and it showed default-rack. Can anyone tell me what I'm doing wrong? Thanks, tim
