-----------------------------------------------------------------
I have been trying to install hadoop on my linux machine to create a
development environment, and I have been following instructions on this page:
http://wiki.apache.org/hadoop/Running_Hadoop_On_Ubuntu_Linux_%28Single-Node_Cluster%29
However, I could not proceed with the installation because of a group ID that
my system associates with my user name, breaks hadoop. As an example, if I run:
$ bin/hadoop dfs -ls
I get the following error:
08/10/16 13:10:13 WARN fs.FileSystem: uri=hdfs://localhost:54310
javax.security.auth.login.LoginException: Login failed: id: cannot find name
for group ID 1106734464

Here, "1106734464" is a group ID that my username belongs to. When I type
$ groups
I get
hadoop id: cannot find name for group ID 1106734464
1106734464
Here, "hadoop" is a username that I created for running hadoop. Similarly, if I
run:
$ id
I get:
uid=501(hadoop) gid=501(hadoop) groups=501(hadoop),1106734464
Is this a bug in hadoop?
