Subject [jira] [Created] (HDFS-3167) CLI-based driver for MiniDFSCluster
Date Fri, 30 Mar 2012 21:25:27 GMT
CLI-based driver for MiniDFSCluster
-----------------------------------

                 Key: HDFS-3167
                 URL: https://issues.apache.org/jira/browse/HDFS-3167
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: test
            Reporter: Henry Robinson
            Assignee: Henry Robinson
            Priority: Minor
             Fix For: 0.24.0


Picking up a thread again from MAPREDUCE-987, I've found it very useful to have a CLI driver
for running a single-process DFS cluster, particularly when developing features in HDFS clients.
For example, being able to spin up a local cluster easily was tremendously useful for correctness
testing of HDFS-2834. 

I'd like to contribute a class based on the patch for MAPREDUCE-987 we've been using fairly
extensively. Only for DFS, not MR since much has changed MR-side since the original patch.
