The assertion error is due to the fact both shaded and non shaded jars are there in classpath. ``` Caused by: java.lang.AssertionError at org.apache.calcite.avatica.AvaticaUtils.instantiatePlugin(AvaticaUtils.java:229) ~[avatica-1.12.0.jar:1.12.0] at org.apache.calcite.avatica.ConnectionConfigImpl$5.apply(ConnectionConfigImpl.java:392) ~[avatica-1.12.0.jar:1.12.0] at org.apache.calcite.avatica.ConnectionConfigImpl$PropEnv.get_(ConnectionConfigImpl.java:173) ~[avatica-1.12.0.jar:1.12.0] at org.apache.calcite.avatica.ConnectionConfigImpl$PropEnv.getPlugin(ConnectionConfigImpl.java:296) ~[avatica-1.12.0.jar:1.12.0] at org.apache.calcite.avatica.ConnectionConfigImpl$PropEnv.getPlugin(ConnectionConfigImpl.java:282) ~[avatica-1.12.0.jar:1.12.0] at org.apache.calcite.config.CalciteConnectionConfigImpl.typeSystem(CalciteConnectionConfigImpl.java:155) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.jdbc.CalciteConnectionImpl.<init>(CalciteConnectionImpl.java:127) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.jdbc.CalciteJdbc41Factory$CalciteJdbc41Connection.<init>(CalciteJdbc41Factory.java:115) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.jdbc.CalciteJdbc41Factory.newConnection(CalciteJdbc41Factory.java:59) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.jdbc.CalciteJdbc41Factory.newConnection(CalciteJdbc41Factory.java:44) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.jdbc.CalciteFactory.newConnection(CalciteFactory.java:53) ~[calcite-core-1.21.0.jar:1.21.0] at org.apache.calcite.avatica.UnregisteredDriver.connect(UnregisteredDriver.java:138) ~[avatica-1.12.0.jar:1.12.0] at java.sql.DriverManager.getConnection(DriverManager.java:664) ~[?:1.8.0_181] at java.sql.DriverManager.getConnection(DriverManager.java:208) ~[?:1.8.0_181] at org.apache.hive.org.apache.calcite.tools.Frameworks.withPrepare(Frameworks.java:175) ~[hive-exec-4.0.0-SNAPSHOT.jar:4.0.0-SNAPSHOT] at org.apache.hive.org.apache.calcite.tools.Frameworks.withPlanner(Frameworks.java:125) ~[hive-exec-4.0.0-SNAPSHOT.jar:4.0.0-SNAPSHOT] at org.apache.hadoop.hive.ql.parse.CalcitePlanner.logicalPlan(CalcitePlanner.java:1555) ~[hive-exec-4.0.0-SNAPSHOT.jar:?] at org.apache.hadoop.hive.ql.parse.CalcitePlanner.genOPTree(CalcitePlanner.java:540) ~[hive-exec-4.0.0-SNAPSHOT.jar:?] ``` Post ``at java.sql.DriverManager.getConnection(DriverManager.java:664) ~[?:1.8.0_181]`` rather than coming back to ``hive-exec`` it goes back to the non shaded jars ``calcite-core`` The driver gets registered with original jar only so it executes call to the non-shaded ones. Ideally we can remove the original ones for itests?? Removing that takes away that error, but driver registration is done as ``HiveDriver`` and while getting connection it wants a `jdbc:calcite` hard-coded in `Framework` class so it gets a: ``` Caused by: java.sql.SQLException: No suitable driver found for jdbc:calcite: at java.sql.DriverManager.getConnection(DriverManager.java:689) ~[?:1.8.0_181] at java.sql.DriverManager.getConnection(DriverManager.java:208) ~[?:1.8.0_181] at org.apache.hive.org.apache.calcite.tools.Frameworks.withPrepare(Frameworks.java:175) ~[hive-exec-4.0.0-SNAPSHOT.jar:4.0.0-SNAPSHOT] ``` Is there are configuration or workaround for the driver-connection.
