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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
