Allen Wittenauer commented on HDFS-9272:
----------------------------------------
I don't think this is the correct approach. For interactive, client-side
operations, you really want WebHDFS and not RPC due to the compatibility
problems.
> 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
> Components: hdfs-client
> 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.
