> 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
