Subject Still "No groups available for user". How to set groups in mapreduce
Date Fri, 15 May 2015 10:09:45 GMT

1 - I am trying to launch a remote job, so I have set in my hosts where 
MapReduce is running the following params in |core-site.xml| [1].
The remote user that is launching the job is |xeon|. But I still get the 
error [2].

For extra-information, here are the |/tmp| dir [3].


|   <property><name>hadoop.proxyuser.xeon.hosts</name><value>*</value></property>


|2015-05-15 10:00:03,495 WARN org.apache.hadoop.security.UserGroupInformation: No groups available
for user xeon


|$~/Programs/hadoop$ hdfs dfs -ls /tmp/
Found 1 items
drwx------   - xeon supergroup          0 2015-05-15 10:00 /tmp/hadoop-yarn

2 - I have changed the loglevel |INFO| to |DEBUG| in all files that are 
in |$HADOOP_HOME/etc/hadoop|, and restarted hadoop. But I still only get 
logs at INFO level. How can I set the MapReduce and hdfs log level to debug?
