MapReduce, mail # user - Webuser id: no such user

Webuser id: no such user

When I'm trying to access Web UI from Mapreduce 1.0.3, I get this error:

2012-08-08 10:22:52,515 WARN
org.apache.hadoop.security.ShellBasedUnixGroupsMapping: got exception
trying to get groups for user webuser
org.apache.hadoop.util.Shell$ExitCodeException: id: webuser: No such user

where do I change the webuser?

Best regards,

Hi Pedro,

Edit the "dfs.web.ugi" property in hdfs-site.xml. It is by default
"webuser,webgroup".
