------------------------------------------
Thank you Hamza,
That is a very good solution,getting the location of the next/previous block
and reading the rest of the item,then append the result in the block you want
to make complete.That would also come in handy for future queries on that file.
I will look into both solutions and keep the best in terms of efficiency.

> 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
