[jira] [Created] (HDFS-9272) Implement a unix-like cat utility

James Clampffer created HDFS-9272:
-------------------------------------

             Summary: Implement a unix-like cat utility
                 Key: HDFS-9272
                 URL: https://issues.apache.org/jira/browse/HDFS-9272
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: James Clampffer
            Assignee: James Clampffer
            Priority: Minor


Implement the basic functionality of "cat" and have it build as a separate executable.

2 Reasons for this:
We don't have any real integration tests at the moment so something simple to verify that the library actually works against a real cluster is useful.

Eventually I'll make more utilities like stat, mkdir etc.  Once there are enough of them it will be simple to make a C++ implementation of the hadoop fs command line interface that doesn't take the latency hit of spinning up a JVM.
