Steve Loughran commented on HADOOP-5123:
----------------------------------------
looking at this and the configuration options, assuming everything is left to
the XML files themselves.
# set it up on the classpath that you declare the task. Easiest to do, and what
I would start with
# with a confdir attribute that points you at a configuration directory
the second option is more flexible.
If I were to do this (and one of my colleagues is pestering me for it), I'd do
it as a contrib -it depends on both core and mapred, so once they get split up,
it should be downstream of them. Nicely self contained, just need a cluster for
testing. This could be done, incidentally, if the MiniMR cluster classes were
moved from test/mapred to mapred, so I could add a <minimrcluster> task too.

> Project: Hadoop Core
> Issue Type: New Feature
> Affects Versions: 0.21.0
> Environment: Both platforms, Linux and Windows
> Reporter: Steve Loughran

> 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?
