gabrieledarrigo opened a new issue #12074: URL: https://github.com/apache/druid/issues/12074
### Affected Version Apache Druid 0.22.0 Zookeper 3.5 ### Description I'm working on a dockerized Druid cluster, similar to the one defined here: https://github.com/apache/druid/blob/0.22.0/distribution/docker/docker-compose.yml I'm trying to integrate the Apache Ranger extension; I managed to find the undocumented `druid-ranger-security.xml` configuration file (here is another issue that I recently opened: https://github.com/apache/druid/issues/12059) that I correctly mount to the Coordinator `/opt/druid/conf/druid/cluster/_common/` folder, but when I startup the cluster I get back the following error: ``` Problem parsing object at prefix[druid.auth.authorizer.ranger]: Cannot construct instance of org.apache.druid.security.ranger.authorizer.RangerAuthorizer, problem: java.lang.NullPointerException at [Source: UNKNOWN; line: -1, column: -1]. at org.apache.druid.server.initialization.AuthorizerMapperModule.configure(AuthorizerMapperModule.java:57) (via modules: com.google.inject.util.Modules$OverrideModule -> com.google.inject.util.Modules$OverrideModule -> org.apache.druid.server.initialization.AuthorizerMapperModule) at org.apache.druid.server.initialization.AuthorizerMapperModule.configure(AuthorizerMapperModule.java:57) (via modules: com.google.inject.util.Modules$OverrideModule -> com.google.inject.util.Modules$OverrideModule -> org.apache.druid.server.initialization.AuthorizerMapperModule) while locating org.apache.druid.server.security.AuthorizerMapper for the 1st parameter of org.apache.druid.security.basic.authorization.db.updater.CoordinatorBasicAuthorizerMetadataStorageUpdater.<init>(CoordinatorBasicAuthorizerMetadataStorageUpdater.java:116) at org.apache.druid.security.basic.authorization.db.updater.CoordinatorBasicAuthorizerMetadataStorageUpdater.class(CoordinatorBasicAuthorizerMetadataStorageUpdater.java:77) while locating org.apache.druid.security.basic.authorization.db.updater.CoordinatorBasicAuthorizerMetadataStorageUpdater at org.apache.druid.security.basic.BasicSecurityDruidModule.createAuthorizerStorageUpdater(BasicSecurityDruidModule.java:158) (via modules: com.google.inject.util.Modules$OverrideModule -> org.apache.druid.security.basic.BasicSecurityDruidModule) at org.apache.druid.security.basic.BasicSecurityDruidModule.createAuthorizerStorageUpdater(BasicSecurityDruidModule.java:158) (via modules: com.google.inject.util.Modules$OverrideModule -> org.apache.druid.security.basic.BasicSecurityDruidModule) while locating org.apache.druid.security.basic.authorization.db.updater.BasicAuthorizerMetadataStorageUpdater Caused by: java.lang.IllegalArgumentException: Cannot construct instance of org.apache.druid.security.ranger.authorizer.RangerAuthorizer, problem: java.lang.NullPointerException ``` Here's my environment file with the authenticator and authorizer configuration (in fact, the same one of the documentation): https://gist.github.com/gabrieledarrigo/f03869706a968f4d05c0412076a668fb And here's my druid-ranger-security.xml: ```xml <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration xmlns:xi="http://www.w3.org/2001/XInclude";> <property> <name>ranger.plugin.druid.service.name</name> <value>ranger</value> <description> Name of the Ranger service containing policies for this SampleApp instance </description> </property> <property> <name>ranger.plugin.druid.policy.source.impl</name> <value>org.apache.druid.security.ranger.authorizer.RangerAdminClientImpl</value> <description> Policy source. </description> </property> <property> <name>ranger.plugin.druid.policy.pollIntervalMs</name> <value>30000</value> <description> How often to poll for changes in policies? </description> </property> <property> <name>ranger.plugin.druid.policy.cache.dir</name> <value>${project.build.directory}</value> <description> Directory where Ranger policies are cached after successful retrieval from the source </description> </property> </configuration> ``` Someone got any idea on what is causing the exception? -- This is an automated message from the Apache Git Service.
