-------------------------------------------
Summary: Metamodel throws a UnsupportedOperationException for
documents containing nested JSON in ElasticSearch
Key: METAMODEL-225
URL: https://issues.apache.org/jira/browse/METAMODEL-225
Project: Apache MetaModel
Issue Type: Bug
Reporter: Akash Suryawanshi
I am using metamodel to connect to elastic search. I created a document in an
index
{code}
PUT /megacorp/employee/1
{
"email": "[email protected]",
"first_name": "John",
"last_name": "Smith",
"info": {
"bio": "Eco-warrior and defender of the weak",
"age": 25,
"interests": [ "dolphins", "whales" ]
},
"join_date": "2014/05/01"
}
I create a DataSet and call the getRow method on it. I get the following
exception
{code}
java.lang.UnsupportedOperationException: JsonObject
at com.google.gson.JsonElement.getAsString(JsonElement.java:191)
~[gson-2.2.4.jar:na]
at
org.apache.metamodel.elasticsearch.rest.JestElasticSearchUtils.getDataFromColumnType(JestElasticSearchUtils.java:72)
~[MetaModel-elasticsearch-rest-4.5.0.jar:4.5.0]
at
org.apache.metamodel.elasticsearch.rest.JestElasticSearchUtils.createRow(JestElasticSearchUtils.java:50)
~[MetaModel-elasticsearch-rest-4.5.0.jar:4.5.0]
at
org.apache.metamodel.elasticsearch.rest.JestElasticSearchDataSet.getRow(JestElasticSearchDataSet.java:126)
~[MetaModel-elasticsearch-rest-4.5.0.jar:4.5.0]
{code}
However this exception does not occur when the document is a simple JSON i.e..
no nested JSON with any of the fields.
