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.
> Evaluate DAG specification using a text format

>
> 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.
