jon-wei opened a new pull request #8652: Fix missing jackson jars for hadoop ingestion URL: https://github.com/apache/incubator-druid/pull/8652 This PR adds the following jars back to druid-hdfs-storage (pruned in #8230) due to observing issues with hadoop ingestion when they're missing: ``` jackson-jaxrs-1.9.13.jar jackson-xc-1.9.13.jar ``` It also adds an explicit dependency on `jackson-core-asl-1.9.13` to `indexing-hadoop`, this is currently being brought in through the Curator 4.1.0 dependency, but it's needed when using Hadoop/HDFS: ``` 2019-10-08T21:04:19,977 WARN [main] org.apache.hadoop.util.NativeCodeLoader - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 2019-10-08T21:04:20,463 WARN [main] org.apache.hadoop.fs.FileSystem - Cannot load filesystem: java.util.ServiceConfigurationError: org.apache.hadoop.fs.FileSystem: Provider org.apache.hadoop.hdfs.web.WebHdfsFileSystem could not be instantiated 2019-10-08T21:04:20,463 WARN [main] org.apache.hadoop.fs.FileSystem - java.lang.NoClassDefFoundError: org/codehaus/jackson/map/ObjectMapper 2019-10-08T21:04:20,463 WARN [main] org.apache.hadoop.fs.FileSystem - java.lang.ClassNotFoundException: org.codehaus.jackson.map.ObjectMapper 2019-10-08T21:04:20,463 WARN [main] org.apache.hadoop.fs.FileSystem - Cannot load filesystem: java.util.ServiceConfigurationError: org.apache.hadoop.fs.FileSystem: Provider org.apache.hadoop.hdfs.web.SWebHdfsFileSystem could not be instantiated 2019-10-08T21:04:20,464 WARN [main] org.apache.hadoop.fs.FileSystem - java.lang.NoClassDefFoundError: org.apache.hadoop.hdfs.web.WebHdfsFileSystem Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/jackson/JsonGenerator at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Class.java:2701) at java.lang.Class.getDeclaredMethods(Class.java:1975) at com.google.inject.spi.InjectionPoint.getInjectionPoints(InjectionPoint.java:688) at com.google.inject.spi.InjectionPoint.forInstanceMethodsAndFields(InjectionPoint.java:380) at com.google.inject.spi.InjectionPoint.forInstanceMethodsAndFields(InjectionPoint.java:399) at com.google.inject.internal.BindingBuilder.toInstance(BindingBuilder.java:84) at org.apache.druid.storage.hdfs.HdfsStorageDruidModule.configure(HdfsStorageDruidModule.java:122) at com.google.inject.spi.Elements$RecordingBinder.install(Elements.java:340) at com.google.inject.spi.Elements.getElements(Elements.java:110) at com.google.inject.util.Modules$OverrideModule.configure(Modules.java:198) at com.google.inject.AbstractModule.configure(AbstractModule.java:62) at com.google.inject.spi.Elements$RecordingBinder.install(Elements.java:340) at com.google.inject.spi.Elements.getElements(Elements.java:110) at com.google.inject.internal.InjectorShell$Builder.build(InjectorShell.java:138) at com.google.inject.internal.InternalInjectorCreator.build(InternalInjectorCreator.java:104) at com.google.inject.Guice.createInjector(Guice.java:99) at com.google.inject.Guice.createInjector(Guice.java:73) at com.google.inject.Guice.createInjector(Guice.java:62) at org.apache.druid.initialization.Initialization.makeInjectorWithModules(Initialization.java:419) at org.apache.druid.cli.GuiceRunnable.makeInjector(GuiceRunnable.java:69) at org.apache.druid.cli.ServerRunnable.run(ServerRunnable.java:56) at org.apache.druid.cli.Main.main(Main.java:113) Caused by: java.lang.ClassNotFoundException: org.codehaus.jackson.JsonGenerator at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 23 more ``` This PR has: - [x] been self-reviewed. - [x] been tested in a test Druid cluster.
