### DefaultDimensionSpec
Returns dimension values as is and optionally renames renames the dimension.

```json
{
"type" : "extraction",

"outputName" : <output_name>,
"dimExtractionFn" : <dim_extraction_fn>
}
```
## DimExtractionFn
`DimExtractionFn`s define the transformation applied to each dimenion value
### RegexDimExtractionFn
Returns the first group matched by the given regular expression. If there is no match it returns the dimension value as is.
```json
{ "type" : "regex", "expr", <regular_expression> }
```
### PartialDimExtractionFn
Returns the dimension value as is if there is a match, otherwise returns null.
```json
{ "type" : "partial", "expr", <regular_expression> }
```
### SearchQuerySpecDimExtractionFn
Returns the dimension value as is if the given [SearchQuerySpec](SearchQuerySpec.html) matches, otherwise returns null.
```json
{ "type" : "searchQuery", "query" : <search_query_spec> }
```
### TimeDimExtractionFn
Parses dimension values as timestamps using the given input format, and returns them formatted using the given output format. Time formats follow the [com.ibm.icu.text.SimpleDateFormat](http://icu-project.org/apiref/icu4j/com/ibm/icu/text/SimpleDateFormat.html) format
```json

### JavascriptDimExtractionFn
Returns the dimension value as transformed by the given JavaScript function.
Example
```json
{

"function" : "function(str) { return str.substr(0, 3); }"

The Hadoop Index Config submitted as part of an Hadoop Index Task is identical to the Hadoop Index Config used by the `HadoopBatchIndexer` except that three fields must be omitted: `segmentOutputPath`, `workingPath`, `updaterJobSpec`. The Indexing Service takes care of setting these fields internally.
##### Using your own Hadoop distribution
Druid is compiled against Apache hadoop-core 1.0.3. However, if you happen to use a different flavor of hadoop that is API compatible with hadoop-core 1.0.3, you should only have to change the hadoopCoordinates property to point to the maven artifact used by your distribution.
##### Resolving dependency conflicts running HadoopIndexTask
Currently, the HadoopIndexTask creates a single classpath to run the HadoopDruidIndexerJob, which can lead to version conflicts between various dependencies of Druid, extension modules, and Hadoop's own dependencies.
The Hadoop index task will put Druid's dependencies first on the classpath, followed by any extensions dependencies, and any Hadoop dependencies last.
If you are having trouble with any extensions in HadoopIndexTask, it may be the case that Druid, or one of its dependencies, depends on a different version of a library than what you are using as part of your extensions, but Druid's version overrides the one in your extension. In that case you probably want to build your own Druid version and override the offending library by adding an explicit dependency to the pom.xml of each druid sub-module that depends on it.
#### Realtime Index Task
The indexing service can also run real-time tasks. These tasks effectively transform a middle manager into a real-time node. We introduced real-time tasks as a way to programmatically add new real-time data sources without needing to manually add nodes. The grammar for the real-time task is as follows:
