Tools to analyze and debug namenode on a production cluster
-----------------------------------------------------------

                 Key: HADOOP-1133
                 URL: https://issues.apache.org/jira/browse/HADOOP-1133
             Project: Hadoop
          Issue Type: Improvement
          Components: dfs
            Reporter: dhruba borthakur
         Assigned To: dhruba borthakur


I would like to have a tool that dumps namenode data structures to a log file. This is especially
useful in debugging a production cluster where attaching a debugger to the namenode is not
a feasible option.
