Description
Using Apache Calcite on Windows and trying to query the DEPTS.csv used on the website tutorial I get a NullPointerException when using Calcite Core 1.13.0 but when I use 1.12.0 the issue disappears.
Properties info = new Properties(); info.put("model", "../src/test/resources/files.json"); info.setProperty("lex", "JAVA"); Connection connection = DriverManager.getConnection("jdbc:calcite:", info); Statement stmt = connection.createStatement(); String sql = "select * from FILES.DEPTS"; ResultSet rs = stmt.executeQuery(sql); while(rs.next()) { System.out.println(rs.getString(1)); }
And the exception is as follows:-
java.sql.SQLException: Error while executing SQL "select * from FILES.DEPTS": null at org.apache.calcite.avatica.Helper.createException(Helper.java:56) at org.apache.calcite.avatica.Helper.createException(Helper.java:41) at org.apache.calcite.avatica.AvaticaStatement.executeInternal(AvaticaStatement.java:156) at org.apache.calcite.avatica.AvaticaStatement.executeQuery(AvaticaStatement.java:218) at za.co.bb8.CalciteTests.testConnection(CalciteTests.java:24) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.NullPointerException at org.apache.calcite.plan.volcano.VolcanoPlanner.validate(VolcanoPlanner.java:891) at org.apache.calcite.plan.volcano.VolcanoPlanner.register(VolcanoPlanner.java:866) at org.apache.calcite.plan.volcano.VolcanoPlanner.ensureRegistered(VolcanoPlanner.java:883) at org.apache.calcite.plan.volcano.VolcanoPlanner.ensureRegistered(VolcanoPlanner.java:101) at org.apache.calcite.rel.AbstractRelNode.onRegister(AbstractRelNode.java:336) at org.apache.calcite.plan.volcano.VolcanoPlanner.registerImpl(VolcanoPlanner.java:1496)
