-----------------------------------
Summary: fuse-dfs does not respect HADOOP_USER_NAME envvar with
simple auth
Key: HDFS-15034
URL: https://issues.apache.org/jira/browse/HDFS-15034
Project: Hadoop HDFS
Issue Type: Improvement
Components: fuse-dfs
Reporter: Istvan Fajth
In the fuse code, there is an explicit map fro the context uid to the username
on the OS level with the help of getpwuid() system call.
As we have already a way to access the callers environment, to determine the
kerberos ticket cache path, we can respect the HADOOP_USER_NAME setting in a
SIMPLE_AUTH based environment, so that the host where the mount is does not
need to have all the users that are defined and used on HDFS.
