sql4es driver seems to be no longer updated, potentially since Elastic provides now an SQL implementation and respective drivers for it.
Oracle Analytics Desktop seems to provide no documentation on integrating 3rd party JDBC drivers and a quick attempt on various ways to configure a source with Elastic's JDBC driver failed.
Furthermore, the proxy providing ODBC connectivity implements an antique version of the API (v 2) and has a number of quirks (tripping on valid DSN names, invoking the API in now explicitly non-recommend ways, not listing valid table names etc.).
Bottom line, @Igor_Motov's comment is pretty valid at this point.
