Elasticsearch 1.3.2 Java api setScript在执行时引发异常

Question

In Elasticsearch java api version 1.3.2, the "setScript()" method does not work by default, like the examples given in Elasticsearch home site. I tried the following, but it threw an exception on execution.

UpdateResponse ur = null;
Map par = new HashMap();
par.put("nsite", "newfield");
par.put("docid", "56783");
ur = client.prepareUpdate(index, type, id)
     .setScriptParams(par)
     .setScript("ctx._source.sites.nsite=docid",ScriptService.ScriptType.INLINE)
     .execute().actionGet();                
System.out.println("updated for "+site);

(Note:- in latest version, Elasticsearch requires two params for "setScript" method) .setScript("ctx._source.sites.nsite=docid") => wrong method signature, script type is mandatory param now.

On running this i got the "Execution exception" as follows:

It seems, the script language by default is not groovy for some reason in newer versions of es. Need to provide that too explicitly. SO, on providing the script language it worked now. (Note:- setScriptLang("groovy") is the required param if groovy is your choice of script in es).

UpdateResponse ur = null;
Map par = new HashMap();
par.put("nsite", "newfield");
par.put("docid", "56783");
ur = client.prepareUpdate(index, type, id)
     .setScriptLang("groovy")
     .setScriptParams(par)
     .setScript("ctx._source.sites.nsite=docid",ScriptService.ScriptType.INLINE)
     .execute().actionGet();                
System.out.println("updated for "+site);
