---------------------------------------------

> Patch includes fix for all the bugs reported in this JIRA except for ...

Thanks, Srikanth.  Could you update the description and the summary of this issue to reflect
all the changes?  (If it is not too hard, it would be great if you could separate the divide
patch to some other issues like HDFS-1009.  In general, a JIRA should only fix one issue.)

> 1. hadoop-version is not recognized if run ant command from src/contrib/ or from src/contrib/hdfsproxy
 
> If running ant command from $HADOOP_HDFS_HOME, hadoop-version will be passed to contrib's
build through subant. But if running from src/contrib or src/contrib/hdfsproxy, the hadoop-version
will not be recognized. 
> 2. ssl.client.do.not.authenticate.server setting can only be set by hdfs's configuration
files, need to move this setting to ssl-client.xml.
> 3.  Solve some race conditions for LdapIpDirFilter.java. (userId, groupName, and paths
need to be moved to doFilter() instead of as class members
> 4. Addressed the following StackOverflowError. 
> ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localh
> ost].[/].[proxyForward]] Servlet.service() for servlet proxyForward threw exception
> java.lang.StackOverflowError
>         at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpR
> equest.java:229)
>      This is due to when the target war (/target.war) does not exist, the forwarding
war will forward to its parent context path /, which defines the forwarding war itself. This
cause infinite loop.  Added "HDFS Proxy Forward".equals(dstContext.getServletContextName()
in the if logic to break the loop.
