[jira] Commented: (HADOOP-5687) Hadoop NameNode throws NPE if fs.default.name is the default value

["Suresh Srinivas (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-5687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699470#action_12699470 ] 

Suresh Srinivas commented on HADOOP-5687:
-----------------------------------------

# Make {{DFS_URI_SCHEME}} final 
# {{NameNode.getAddress()}} 
#* use authority that you already have to return as {{getAddress(authority)}}
#* use {{FS_DEFAULT_NAME_KEY}} instead of hardcoded conf name {{"fs.default.name"}}
# Hard coded "hdfs" can be replaced with {{DFS_URI_SCHEME}} in {{SecondaryNameNode.getInforServer()}}

> Throwing NPE is confusing; instead, an exception with a useful string description could be thrown instead.
