Keep Coding

We have below mapping defined for my index -
{
"mappings": {
"data": {
"_source": {
"enabled": true
},
"properties": {
"attributeNames": {
"type": "string"
},
"attributes": {
"type": "nested",
"include_in_parent": true,
"properties": {
"mc_name": {
"type":"string"
},
"mc_original_severity": {
"type": "string",
"index": "not_analyzed",
"fields": {
"converted": {
"type": "string",
"index": "not_analyzed"
}
}
},
"mc_score": {
"type": "integer"
}
}
}
}
}
}
}
We want that while indexing data into this index, based on the value of "mc_original_severity" we want to set the value of "mc_original_severity.converted". Previously we were using ES 1.7 and in that we have written groovy script and put that Groovy script inside Transform property of Mapping something like this -
"transform": {
"script": " if (ctx._source.attributes.mc_original_severity?.equals('CRITICAL')) {ctx._source['mc_original_severity.converted'] = '0';} ;",
"lang": "groovy"
}
Currently, we are using ES 5.2 and we are using Pipeline and script processor. We want to do the same thing using script processor either using Painless scripting or Groovy scripting. Below is the code which we are using right now -
String completeScript = "if (ctx._type.equals('data')) { if (ctx.mc_original_severity.equals('MODERATE')) {ctx.doc['mc_original_severity.converted'] = '0';}"
+ "else if(ctx.mc_original_severity.equals('CRITICAL')){ctx.doc['mc_original_severity.converted'] = '1';} };";
PutPipelineRequestBuilder reqBuilder = getPipelineRequestBuilder(localClient, action, "pipe1", completeScript);
reqBuilder.execute().get();
private static PutPipelineRequestBuilder getPipelineRequestBuilder(Client client, PutPipelineAction putPipelineAction,
String pipeName, String completeScript){
PutPipelineRequestBuilder reqBuilder = new PutPipelineRequestBuilder(localClient, putPipelineAction, "pipe1",
new BytesArray(
"{\n"+
" \"processors\": [\n"+
" {\n"+
" \"script\": {\n"+
" \"lang\": \"groovy\",\n"+
" \"inline\": \""+completeScript+"\"\n"+
" }\n"+
" }\n"+
" ]\n"+
"}\n"));
return reqBuilder;
But the script which we are using is not working right now while we ingest data after applying this pipeline. We have tried different combinations of Groovy as well as Painless script. Can somebody guide us how to achieve the use case described above. We are getting below exception for above used script.
