      Description

      Bugs:

      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. LdapIpDirFilter.java is not thread safe. userName, Group & Paths are per request and can't be class members.

      3. 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.

      4. Kerberos credentials of remote user aren't available. HdfsProxy needs to act on behalf of the real user to service the requests
