Hi all

I'm working with Cascading and ES-Hadoop connector, using an Hfs source and an ES sink on a Hadoop2MR1FlowConnector with following properties:

```
props.setProperty(ConfigurationOptions.ES_WRITE_OPERATION, ConfigurationOptions.ES_OPERATION_UPSERT);
props.setProperty(ConfigurationOptions.ES_UPDATE_SCRIPT, esUpdateScript);
props.setProperty(ConfigurationOptions.ES_UPDATE_SCRIPT_LANG, "groovy");

new Hadoop2MR1FlowConnector(props).connect(hfsTap, esTap, tailPipe).complete();

```

I see there is a config option to set script parameters: `ConfigurationOptions.ES_UPDATE_SCRIPT_PARAMS_JSON`

My question is, How can I use output tuple values (from tailPipe) as parameters in the groovy script?

Thanks

If you want to know more about the various configuration options you can:

1. look at the official reference [docs](https://www.elastic.co/guide/en/elasticsearch/hadoop/master/configuration.html#cfg-update)
2. if looking at the sources, take a look at the test suite

Note that the params are static - they can either be constant values or extracted from the document passed to ES.  
If your tuple is passed as the sink/tap to be written, then one can extract it from it - if not, then you'll have to device your own custom solution.
