Amareshwari Sriramadasu updated HADOOP-3743:
--------------------------------------------
Attachment: patch-3743.txt
Here is patch with:
* Removed code for Parser and Options in JobShell.
* TestJobShell is modified not to create temporary file (files_tmp) in the cwd
bq. also since the generic options parser always does the parsing — in case of
JobShell as well — the property conf.set("mapred.used.genericoptionsparser",
"yes"); will always be set? right?
Yes. The static configuration has _mapred.used.genericoptionsparser_ value set
to yes.
bq. In that case it will always print the warning always.
Warning will not be printed, because JobClient checks for the configuration
property in JobConf submitted to the _submitJob_. And
_mapred.used.genericoptionsparser_ will be set in JobConf, submitted to the
_submitJob_, only if the application is implementing Tool. Thus applications
not implementing Tool will be warned to do the same.
bq.3)Here is a problem -
In case 1) -libjars is passed by JobShell. In case 2) -libjars is parsed by
application.
bq. If JobShell does not parse -libjars in case 2) then we can print the
warning in JobShell if the properties of libjars and others are set in JobShell.
No. Because the actual parsing is done by GenericOptionsParser.
> -libjars, -files and -archives options do not work with 0.18

> I am not sure how to get -libjars and -files working with 0.18. I tried all
> the options but cannot get it runnning. I am filing this as a blocker until
> we find out that its not broken. -- in that case we need to update the docs
> with an example to say how it works.
