Hi,

I’m chen, working in the same team as lu jander.

Actually , we’re planning to implement the common lib management base on bp 
expose-elements<https://blueprints.launchpad.net/sahara/+spec/expose-elements>.

We would like to build common supported 3-rd part libs into sahara images, so 
user do not need to upload these libs themselves, and each lib would be an 
element which would be an attribute value for a running  cluster.

The improve for oozie engine is used for other “common libs” user want to use 
but could not be found in Sahara image. User do has the ability to upload them 
to sahara by themselves, and it would be implemented based on job binaries.

With a user friendly interface to let user know what libs are available on 
currently running cluster which would combine these libs already in images and 
uploaded by users, user only need to pick up libs they want to use.

Oozie.libpath would be set automately by sahara based on the libs user chose.


Thanks.
-chen

Hi Sergey
yes, it is based on job binaries. what we should do is provide a user friendly 
interface, to let user know how to set oozie.libpath( may be we can show it as 
"share lib path" in the job execution config horizon page)  there are two 
scenarios as below:
(1) if Job A and Job B all need lib A, we can upload lib A through job binary 
into sahara, then before we run Job A and B, user can set oozie.libpath to the 
path where lib A exists.
(2) if Job A and Job B need system lib or other libs already exists in the OS, 
user needs not to upload additional job binary

Hi,

do you think it could be implemented based on job binaries? It sounds like it's 
a type of job binary that should be always uploaded to Oozie for the tenant 
where it lives. (A bit crazy, but could useful).

Thanks.

Hi, All
Currently, oozie share lib is not well known and can be hardly used by the 
users, so I think we can  make it less oozieness and more friendly for the 
users, it can be used for running jobs which are using third party libs. If 
many jobs use the same libs, oozie share lib can make it as a common share lib.

here is the bp, 
https://blueprints.launchpad.net/sahara/+spec/improve-oozie-share-lib
I will write a spec soon after scheduled edp jobs bp.
