Rajesh Balamohan updated TEZ-1100:
----------------------------------
    Attachment: TEZ-1100.WIP.1.patch

Uploading a WIP patch which lets user to express the DAG as XML (based on dag.xsd).  Patch contains some of the tez examples which have been ported to XML.  There are some known limitations where userPayload can't be directly expressed in byte[] as in Tez.  But this can be a initial start to express the DAG easily in XML.  Early reviews are welcome.

> It may be useful to specify the DAG using a text format (eg. xml). A generic translator could be written to turn this into a DAG via the Java Tez API.
> Benefits
> 1) Lowers bar for entry. Allow people to specify jobs without writing or compiling code
> 2) De-couples the user language from the Tez library language. Allows non-Java front ends that could translate to the text format.
