Hi, I am new to Apache Drill and start to study the Drill RPC protocol recently. I try to follow Michael's instruction to run Apache Drill I a 3-node clusters
https://github.com/mhausenblas/apache-drill-sandbox/tree/master/M1 Instead of downloading the binary tarball, I build the tarball from the source code. $ mvn package Then I start drillbit but get some exceptions: $ ./bin/drillbit.sh start Exception in thread "main" java.lang.NoClassDefFoundError: io/netty/buffer/PooledByteBufAllocatorL at org.apache.drill.exec.memory.DirectBufferAllocator.<init>(DirectBufferAllocator.java:27) at org.apache.drill.exec.memory.BufferAllocator.getAllocator(BufferAllocator.java:84) at org.apache.drill.exec.server.BootStrapContext.<init>(BootStrapContext.java:44) at org.apache.drill.exec.server.Drillbit.<init>(Drillbit.java:85) at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:50) at org.apache.drill.exec.server.Drillbit.start(Drillbit.java:43) at org.apache.drill.exec.server.Drillbit.main(Drillbit.java:65) Caused by: java.lang.ClassNotFoundException: io.netty.buffer.PooledByteBufAllocatorL 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) ... 7 more Exception in thread "ShutdownHook" java.lang.NullPointerException at org.apache.drill.exec.server.Drillbit.close(Drillbit.java:105) at org.apache.drill.exec.server.Drillbit$ShutdownThread.run(Drillbit.java:125) It seems that the generated binary tarball missed the following jar files: exec/bufferl/target/drill-netty-bufferl-4.0.7.Final.jar exec/ref/target/drill-ref-1.0.0-m2-incubating-SNAPSHOT.jar sqlparser/target/drill-sqlparser-1.0.0-m2-incubating-SNAPSHOT.jar My solution is to modify "distribution/src/assemble/bin.xml " to add missing jars to tarball. I attached the patch here. Is that the correct way to do it? Thanks, Xiao
