---------------------------------
Summary: ElasticSearch Date types should be converted properly
Key: METAMODEL-172
URL: https://issues.apache.org/jira/browse/METAMODEL-172
Project: Apache MetaModel
Issue Type: Bug
Reporter: Alberto
Priority: Critical
When working with ElasticSearch indexes that contains Date types the API is
returning Strings instead of proper Date object.
We should add some logic inside the ElasticSearchUtils createRow() method to
convert these strings to java.Date objects. As we are not doing this conversion
so far the TimeComparator convertFromString method is not able to parse the
string value as a Date, the method returns null and then the FormatHelper class
is throwing an IllegalStateException.
This is a bit tricky though because the number of date formats supported by
ElasticSearch is quite big to think about creating a SimpleDateFormat to
support every single case:
