----------------------------------------------------------
[~szetszwo], usually we use the same name for the variable and its value, but
looks like we are not consistent in DFSConfigKeys.java, for example:
DFS_DATANODE_USER_NAME_KEY, DFS_NAMENODE_USER_NAME_KEY and etc. Not sure why
these variables were named differently with their values. In one place, we are
consistent:
DFS_WEB_AUTHENTICATION_KERBEROS_PRINCIPAL_KEY =
"dfs.web.authentication.kerberos.principal";
If we don't have a good reason to name the variables differently, I can update
all of the following to make the name the same as value:
DFS_NAMENODE_USER_NAME_KEY, DFS_DATANODE_USER_NAME_KEY,
DFS_JOURNALNODE_USER_NAME_KEY, DFS_SECONDARY_NAMENODE_USER_NAME_KEY,
DFS_NFS_USER_NAME_KEY
