Steve Loughran updated HADOOP-5123:
-----------------------------------
Attachment: JobSubmitTask.java
This is a first draft of a JobSubmit client.
1. no declaration/setting up of the inputs and outputs
2. no setup, yet, of the configuration above the default values.
For #2 there's a choice.
(a) refer to an ant resource (including, once its in there, a resource in an
HDFS filesystem)
(b) let you declare the various properties in Ant itself.
(b) is more Ant-like, but less compatible with the rest of the hadoop
configuration design, and may still need to support reading in XML files just
to get the base configuration together. But a mixed-configuration is hardest to
get right.
Thoughts?

> 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?
