[Groovy script] java.lang.NoClassDefFoundError:

[mekanixdk]

I am trying to execute a groovy-script I have stored on the server, and I get this error, that almost sound like some groovy related library is missing from the image?

{
  "error": {
    "root_cause": [
      {
        "type": "script_exception",
        "reason": "failed to run file script [sort_by_array_index] using lang [groovy]"
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "development_1",
        "node": "IxIgjCSmR_SW_5Jj468IOA",
        "reason": {
          "type": "script_exception",
          "reason": "failed to run file script [sort_by_array_index] using lang [groovy]",
          "caused_by": {
            "type": "bootstrap_method_error",
            "reason": "java.lang.NoClassDefFoundError: org/codehaus/groovy/runtime/wrappers/Wrapper",
            "caused_by": {
              "type": "no_class_def_found_error",
              "reason": "org/codehaus/groovy/runtime/wrappers/Wrapper",
              "caused_by": {
                "type": "class_not_found_exception",
                "reason": "org.codehaus.groovy.runtime.wrappers.Wrapper"
              }
            }
          }
        }
      }
    ]
  },
  "status": 500
}

Or is there something I need to install? Groovy is built in AFAIK.

Dockerfile

FROM elasticsearch:2.2

RUN plugin install analysis-icu &&\
    plugin install lmenezes/elasticsearch-kopf/2.x &&\
    plugin install delete-by-query

COPY sort_by_array_index.groovy /usr/share/elasticsearch/config/scripts

sort_by_array_index.groovy

def lowestIdx = ids.size()+1;
def idx = -1;
for (v in doc[fieldName].values) {
    idx = ids.indexOf((Integer)v);
    if (idx != -1 && lowestIdx > idx) {
        lowestIdx = idx;
    }
};
return lowestIdx;

And the trigger part in search query:

"sort": [
    {
      "_script": {
        "lang": "groovy",
        "type": "number",
        "order": "asc",
        "script": {
          "file": "sort_by_array_index",
          "params": {
            "fieldName": "list",
            "ids": [1,2,3,4,5]
          }
        }
      }
    }
  ]

I have downgraded from Elasticsearch 2.2 to 2.1 and now the script works.

Hmm, could it be this: https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-2.2.html#_scripting_and_security that is biting me?

[jurgc11]

I found adding
permission org.elasticsearch.script.ClassPermission "org.codehaus.groovy.runtime.wrappers.Wrapper";
into
$ES_HOME/modules/lang-groovy/plugin-security.policy
fixed this for me. I think there are still a few things missing from this file by default, i've had to add a couple of permissions into this file already just to get basic Groovy stuff working.

[mekanixdk]

I ended up doing:

ENV JAVA_OPTS="${JAVA_OPTS} -Djava.security.policy=file:///usr/share/elasticsearch/config/groovy_classes_whitelist.policy"

in dockerfile while groovy_classes_whitelist.policy contains:

grant {
    permission org.elasticsearch.script.ClassPermission "org.codehaus.groovy.runtime.wrappers.Wrapper";
};

and copied to /usr/share/elasticsearch/config/groovy_classes_whitelist.policy

This way I avoided having to overwrite/edit existing files from the parent docker image and having to keep tabs on changes to those.
