["Davor Bonaci (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-1691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15925408#comment-15925408 ] 

Davor Bonaci commented on BEAM-1691:
------------------------------------

[~mingmxu], can you say more please?

Generally speaking, runners may require different pipeline options. Options are provided by individual runners and they have to be on the classpath to be able to set such options. If users wants multiple runners on the classpath, this will just work -- options for multiple runners can be set.

However -- users need to tweak at least one option: --runner. Tweaking any runner-specific along the way isn't that different.

> Usually the two lines to create a new Beam pipeline are:
> {code}
> Options options = PipelineOptionsFactory.fromArgs(args).withValidation().as(Options.class);
> Pipeline pipeline = Pipeline.create(options);
> {code} 
> As each runner has its own PipelineOptions, one piece of code is hardly to run on different runners without code change, --as least Options needs to be updated.
> Dynamic property could be a choice, similar as
> {code}
> -D property1=value1 -D property2=value2 ...
> {code}
