Summary: Drill JDBC driver fails on Java 1.9+ with NoClassDefFoundError: sun/misc/VM Key: DRILL-6349 URL: https://issues.apache.org/jira/browse/DRILL-6349 Project: Apache Drill Issue Type: Bug Components: Client - JDBC Affects Versions: 1.13.0 Environment: 16:23 apache-drill-1.13.0$ uname -a Darwin bix.local 17.5.0 Darwin Kernel Version 17.5.0: Mon Mar 5 22:24:32 PST 2018; root:xnu-4570.51.1~1/RELEASE_X86_64 x86_64 Reporter: Marc Prud'hommeaux I'm surprised to be unable to find this issue logged elsewhere, but a quick search yields nothing. Trying to connect with the JDBC driver raises a NoClassDefFoundError for sun.misc.VM, which was removed in Java 9. It is understandable that the full drillbit (or its many dependencies) may have difficult-to-extract dependencies on some sun.misc.* classes, but the JDBC driver should be able to be loaded by any JVM. Looking at ./common/src/main/java/org/apache/drill/common/config/DrillConfig.java, it appears that a quick workaround could be to make sun.misc.VM.maxDirectMemory called lazily from the one place that uses it: getMaxDirectMemory() {{}}{{16:21 apache-drill-1.13.0$ JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk ./bin/drill-localhost }} ***Connecting to jdbc:drill:drillbit=localhost* WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.apache.calcite.avatica.com.google.protobuf.UnsafeUtil (file:/Users/marc/Downloads/apache-drill-1.13.0/jars/3rdparty/avatica-1.10.0.jar) to field java.nio.Buffer.address WARNING: Please consider reporting this to the maintainers of org.apache.calcite.avatica.com.google.protobuf.UnsafeUtil WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release {{java.lang.NoClassDefFoundError: sun/misc/VM}} {{ at org.apache.drill.common.config.DrillConfig.<clinit>(DrillConfig.java:49)}} {{ at org.apache.drill.jdbc.impl.DrillConnectionImpl.<init>(DrillConnectionImpl.java:155)}} {{ at org.apache.drill.jdbc.impl.DrillJdbc41Factory.newDrillConnection(DrillJdbc41Factory.java:73)}} {{ at org.apache.drill.jdbc.impl.DrillFactory.newConnection(DrillFactory.java:69)}} {{ at org.apache.calcite.avatica.UnregisteredDriver.connect(UnregisteredDriver.java:138)}} {{ at org.apache.drill.jdbc.Driver.connect(Driver.java:72)}} {{ at sqlline.DatabaseConnection.connect(DatabaseConnection.java:168)}} {{ at sqlline.DatabaseConnection.getConnection(DatabaseConnection.java:214)}} {{ at sqlline.Commands.connect(Commands.java:1083)}} {{ at sqlline.Commands.connect(Commands.java:1015)}} {{ at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)}} {{ at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)}} {{ at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)}} {{ at java.base/java.lang.reflect.Method.invoke(Method.java:564)}} {{ at sqlline.ReflectiveCommandHandler.execute(ReflectiveCommandHandler.java:36)}} {{ at sqlline.SqlLine.dispatch(SqlLine.java:742)}} {{ at sqlline.SqlLine.initArgs(SqlLine.java:528)}} {{ at sqlline.SqlLine.begin(SqlLine.java:596)}} {{ at sqlline.SqlLine.start(SqlLine.java:375)}} {{ at sqlline.SqlLine.main(SqlLine.java:268)}} {{Caused by: java.lang.ClassNotFoundException: sun.misc.VM}} {{ at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:582)}} {{ at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:185)}} {{ at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:496)}} {{... 20 more}} apache drill 1.13.0 "just drill it" 0: jdbc:drill:drillbit=localhost> -- This message was sent by Atlassian JIRA (v7.6.3#76005)
