Hi all,

Situation

following the details on
https://drill.apache.org/docs/using-the-jdbc-driver/
I'm trying to connect

   - with a simple JDBC Client (based on the code on bottom of
   "using-the-jdbc-driver"-page)
   - using the Drill JDBC Driver(
      *./jars/jdbc-driver/drill-jdbc-all-1.2.0.jar* ) in classpath
      - to a locally running embedded drill instance. ( started via
   ./bin/drill-embedded )
   - with connection url:* jdbc:drill:schema=P3.public;zk=local*
      - Drill Storage P3 is of type "jdbc" and connects to a PostgreSQL DB.
      (Remark: Storage P3 is working properly and can be queried in embedded
      Drill shell as expected)

Problem

On startup of the simple JDBC Client, I encounter:

17:36:44 DEBUG FormatPluginConfigBase: Found 0 format plugin configuration
classes: .
17:36:44 DEBUG DrillConfig: DrillConfig object initialized.
[error] (run-main-0) java.lang.NoClassDefFoundError:

Analysis

   - Opening drill-jdbc-all-1.2.0 .jar the path
   /oadd/org/apache/drill/exec/... is missing in the jar.
   - BTW: The same holds for a freshly built drill-1.3.0-snapshot

Questions

   - Is it reasonable (and intented) to connect to an embedded drill
   instance via the JDBC client, like I do? If not, what are the alternatives?
   - Is it a bug (or maybe unintended), that within ./*exec/jdbc-all/pom.xml
   *in the <filter>-section of the shade plugin, "exec/store" (line 408) is
   filtered?
       <exclude>org/apache/drill/exec/store/**</exclude>

Thx for help in advance,

Martin
