You need to use the org.apache.drill.jdbc.Driver class.
The drill-jdbc-all dependency should be enough. Are you trying to connect to an HDFS cluster's
zookeeper?

Hello,
I am working on a maven project that relies on drill-JDBC, for a stand alone project, I used
this dependency (and it connected/ran fine)
<groupId>org.apache.drill.exec</groupId>
<artifactId>drill-jdbc-all</artifactId>
<version>1.10.0</version>
For my actual project, I am using the same dependency and getting this error.
WARN oadd.org.apache.zookeeper.ClientCnxn - Session 0x0 for server null, unexpected error,
closing socket connection and attempting reconnect
java.lang.NoClassDefFoundError: oadd/org/apache/log4j/Logger
Any help is appreciated :)
Also what when should each of these be used?
"org.apache.drill.jdbc.Driver"
"com.mapr.drill.jdbc41.Driver"
