Description
I have zookeeper installed and I'm running a single drillbit.
I'm running a simple Jdbc program that uses drill-jdbc-all, and I do get the following error when trying to connect:
Exception in thread "main" java.lang.NoClassDefFoundError: oadd/org/codehaus/jackson/map/ObjectMapper at oadd.org.apache.curator.x.discovery.details.JsonInstanceSerializer.<init>(JsonInstanceSerializer.java:42) at oadd.org.apache.curator.x.discovery.ServiceDiscoveryBuilder.builder(ServiceDiscoveryBuilder.java:42) at oadd.org.apache.drill.exec.coord.zk.ZKClusterCoordinator.getDiscovery(ZKClusterCoordinator.java:265) at oadd.org.apache.drill.exec.coord.zk.ZKClusterCoordinator.<init>(ZKClusterCoordinator.java:103) at oadd.org.apache.drill.exec.client.DrillClient.connect(DrillClient.java:185) at org.apache.drill.jdbc.impl.DrillConnectionImpl.<init>(DrillConnectionImpl.java:134) at org.apache.drill.jdbc.impl.DrillJdbc41Factory.newDrillConnection(DrillJdbc41Factory.java:66) at org.apache.drill.jdbc.impl.DrillFactory.newConnection(DrillFactory.java:69) at oadd.net.hydromatic.avatica.UnregisteredDriver.connect(UnregisteredDriver.java:126) at org.apache.drill.jdbc.Driver.connect(Driver.java:72) at java.sql.DriverManager.getConnection(DriverManager.java:571) at java.sql.DriverManager.getConnection(DriverManager.java:233) at SimpleJdbc.main(SimpleJdbc.java:13) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140) Caused by: java.lang.ClassNotFoundException: oadd.org.codehaus.jackson.map.ObjectMapper at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 18 more
Using jdbc-all built right before DRILL-3589 commit works fine, so the problem seem to be related to the changes in DRILL-3589
Here is the program I'm running:
import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.Statement; public class SimpleJdbc { public static void main(String[] args) throws Exception { Class.forName("org.apache.drill.jdbc.Driver").newInstance(); Connection conn = DriverManager.getConnection("jdbc:drill:"); Statement stmt = null; ResultSet rs = null; try { stmt = conn.createStatement(); rs = stmt.executeQuery("SELECT employee_id FROM cp.`employee.json`"); while (rs.next()) { System.out.println(rs.getObject(1)); } } finally { if (stmt != null) { stmt.close(); } if (rs != null) { rs.close(); } conn.close(); } } }
