[jira] [Created] (METAMODEL-106) ElasticSearchDataContext throws
NPE when index is not found
Kasper Sørensen created METAMODEL-106:
-----------------------------------------
Summary: ElasticSearchDataContext throws NPE when index is not found
Key: METAMODEL-106
URL: https://issues.apache.org/jira/browse/METAMODEL-106
Project: Apache MetaModel
Issue Type: Bug
Affects Versions: 4.3.0-incubating
Reporter: Kasper Sørensen
If I accidentally use a wrong index name when creating an ElasticSearchDataContext, I get an exception like this:
{code}
java.lang.NullPointerException
at org.apache.metamodel.elasticsearch.ElasticSearchDataContext.detectSchema(ElasticSearchDataContext.java:161)
at org.apache.metamodel.elasticsearch.ElasticSearchDataContext.<init>(ElasticSearchDataContext.java:122)
{code}
I would expect a more meaningful exception - either IllegalArgumentException or a MetaModelException - with a proper explanation as a message.
We should also have sensible checks for null values and empty strings etc.
