Steve Loughran commented on HADOOP-5123:
----------------------------------------
I'll take a look at the codebase in both of these. I'd initially expect to
start with the minimal set of operations needed to get work into a cluster from
a developer's desktop; let it evolve from there. While I know less about Hadoop
than the other contributions, I do know more about Ant and how to test build
files under JUnit, so what's really going to be new here are the regression
tests. I have some job submit code of my own that I was going to start with,
but HADOOP-2788 could be a good starting point.
What worries me is the whole configuration problem; I think the client settings
are minimal enough now that the JT URL should be enough.
The other problem is versioning; I will handle that by requiring tasks and
cluster to be in sync, at least for now.

> Key: HADOOP-5123
> URL: https://issues.apache.org/jira/browse/HADOOP-5123
> Project: Hadoop Core
> Issue Type: New Feature
> Affects Versions: 0.21.0
> Environment: Both platforms, Linux and Windows
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> Ant tasks to make it easy to work with hadoop filesystem and submit jobs.
> <submit> : uploads JAR, submits job as user, with various settings
> filesystem operations: mkdir, copyin, copyout, delete
> -We could maybe use Ant1.7 "resources" here, and so use hdfs as a source or
> dest in Ant's own tasks
> # security. Need to specify user; pick up user.name from JVM as default?
> # cluster binding: namenode/job tracker (hostname,port) or url are all that
> is needed?
> #job conf: how to configure the job that is submitted? support a list of
> <property name="name" value="something"> children
> # testing. AntUnit to generate <junitreport> compatible XML files
> # Documentation. With an example using Ivy to fetch the JARs for the tasks
> and hadoop client.
> # Polling: ant task to block for a job finished?
