Using Apache Drill v1.2 and Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit in embedded mode.

I'm curious if anyone has had any success connecting Apache Drill to an Oracle DB. I've updated the drill-override.conf with the following configurations (per documents):

drill.exec: {
cluster-id: "drillbits1",
zk.connect: "localhost:2181",
drill.exec.sys.store.provider.local.path = "/mypath"
}
and placed the ojdbc6.jar in \apache-drill-1.2.0\jars\3rdparty. I can successfully create the storage plug-in:

{
"type": "jdbc",
"driver": "oracle.jdbc.driver.OracleDriver",
"url": "jdbc:oracle:thin:@<IP>:<PORT>:<SID>",
"username": "USERNAME",
"password": "PASSWORD",
"enabled": true
}
but when I issue a query such as:

select * from <storage_name>.<schema_name>.`dual`;
I get the following error:

Query Failed: An Error Occurred
org.apache.drill.common.exceptions.UserRemoteException: VALIDATION ERROR: From line 1, column 15 to line 1, column 20: Table '<storage_name>.<schema_name>.dual' not found [Error Id: 57a4153c-6378-4026-b90c-9bb727e131ae on <computer_name>:<PORT>].
I've tried to query other schema/tables and get a similar result. I've also tried connecting to Teradata and get the same error.
