> Add input/output formatters for Vertica clustered ADBMS.
> --------------------------------------------------------
>
> Key: MAPREDUCE-775
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-775
> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Reporter: Omer Trajman
> Assignee: Omer Trajman
> Fix For: 0.21.0
>
> Attachments: MAPREDUCE-775.2.patch, MAPREDUCE-775.patch
>
>
> Add native support for Vertica as an input or output format taking advantage
> of parallel read and write properties of the DBMS.
>
> On the input side allow for parametrized queries (a la prepared statements)
> and create a split for each combination of parameters. Also support the
> parameter list to be generated from a sql statement. For example - return
> metrics for all dimensions that meet criteria X with one input split for each
> dimension. Divide the read among any number of hosts in the Vertica cluster.
>
> On the output side, support Vertica streaming load to any number of hosts in
> the Vertica cluster. Output may be to a different cluster than input.
>
> Also includes Input and Output formatters that support streaming interface.
> Code has been tested and run on live systems under 19 and 20. Patch for 21
> with new API will be ready end of this week.
