#### Post date: [July 3, 2014, 5:58pm UTC](https://discuss.elastic.co/t/use-arrays-as-update-parameters-with-elasticsearch-hadoop-mr/18470/1 "2014-07-03T17:58:11Z")
I would like to update an existing document that has an array from
elasticsearch hadoop.
I notice that I can do that from curl directly, for example:
PUT arraydemo/temp/1
{
"counter" : 1,
"tags" : ["I am an array", "With Multiple values"],
"more\_tags" : ["I am a tag"],
"even\_more\_tags": "I am a tag too!"
}
GET arraydemo/temp/1
POST arraydemo/temp/1/\_update
{
"script" : "tmp = new HashSet(); tmp.addAll(ctx.\_source.tags); tmp.addAll(new\_tags); ctx.\_source.tags = tmp.toArray()",
"params" : {
"new\_tags" : ["add me", "and me"]
}
}
However, elasticsearch-hadoop appears to be unable to parse array
parameters, such that an upsert operation from within elasticsearch hadoop
using the same script and a document with the same JSON for parameters
fails.
I created an issue on github (elasticsearch hadoop (#223)), but thought I
should post here for ideas or in case there's a workaround that someone
might know of.

Hi James,
Fwiw, I plan to address this bug shortly - as you pointed out, the JSON
array needs to be handled separately before passing its content in.
