Preston Carman commented on VXQUERY-131:
----------------------------------------
Take a look at the developer's get started page:
http://vxquery.apache.org/developer_get_started.html
Setting up the development environment will allow you to look at the VXQuery
code base. It will also allow you to run queries.
Once you have the system set up and running you can see the job created from a
query by using the command option, "-showrp". Check the other parameters for
VXQuery to see the query plan at different stages.
> Supporting Hadoop data and cluster management

> Key: VXQUERY-131
> URL: https://issues.apache.org/jira/browse/VXQUERY-131
> Project: VXQuery
> Issue Type: Improvement
> Reporter: Preston Carman
> Assignee: Preston Carman
> Labels: gsoc, gsoc2015, hadoop, java, mentor, xml
>
> Many organizations support Hadoop. It would be nice to be able to read data
> from this source. The project will include creating a strategy (with the
> mentor's guidance) for reading XML data from HDFS and implementing it. When
> connecting VXQuery to HDFS, the strategy may need to consider how to read
> sections of an XML file.
> In addition, we could use Yarn as our cluster manager. The Apache Hadoop YARN
> (Yet Another Resource Negotiator) would be a good cluster management tool for
> VXQuery. If VXQuery can read data from HDFS, then why not also manage the
> cluster with a tool provided by Hadoop. The solution would replace the
> current custom python scripts for cluster management.
> Goal
> - Read XML from HDFS
> - Manage the VXQuery cluster with Yarn
