Gabriel Reid commented on CRUNCH-470:
-------------------------------------
Do you mean the addition of a new Pipeline implementation (in addition to
MemPipeline, MRPipeline, and SparkPipeline)? The MRPipeline implementation will
already run on YARN as long as Crunch is compiled for hadoop2, so there
shouldn't be a new Pipeline impl needed for this.
On the other hand, if you're referring to testing pipelines on a
pseudo-distributed mini cluster, that is already possible -- this is what's
actually done in the HFileTargetIT integration test, a mini-cluster (with HDFS,
etc) is spun up and the pipeline is run there.
> Add hdfs/yarn minicluster crunch pipeline

> Key: CRUNCH-470
> URL: https://issues.apache.org/jira/browse/CRUNCH-470
> Project: Crunch
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.8.3
> Reporter: Rafal Wojdyla
> Assignee: Josh Wills
> Priority: Minor
>
> Crunch currently has two pipelines:
> * MemPipeline
> * MRPipeline
> MemPipeline is in-memory pipelines based on local in-memory mapreduce mode.
> MRPipeline is distributed pipeline based on distributed MapReduce.
> Using HDFS/YARN Minicluster it's possible to better emulate Hadoop cluster,
> and it could be a 'final test' before running on the cluster.
