Subject [jira] Commented: (HADOOP-4212) New lines and leading spaces are not trimmed of a value when configuration is read
Date Mon, 22 Sep 2008 11:16:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12633215#action_12633215
] 

Sreekanth Ramakrishnan commented on HADOOP-4212:
------------------------------------------------

Only place it would and should be dependent on is Filesystem path's but does trailing space
make sense with respect to them? Won't it be problematic when looking at windows file system?

With respect to xml:space attribute it would be use only if the parser which we use is a XML
validating parser.  I dont see that we are using XML validating parser when parsing for the
configuration. So should we now parse all configuration using validation turned on? 

Moreover, there is a similar issue reported here [HADOOP-2366|https://issues.apache.org/jira/browse/HADOOP-2366]
