Ciao,   I have performed an upgrade of my cluster using the upgrade feature from Cloudera manager (from 5.8.0 to 5.8.2). I have got 2 issues: Oozie:  Test of whether the correct Oozie Server shared library is installed. Bad : The Oozie Server build version(4.1.0-cdh5.8.2) and the Oozie Server shared library version(4.1.0-cdh5.8.0) do not match.     Sqoop 2 Error: 2016-09-29 16:34:31,692 INFO org.apache.sqoop.repository.JdbcRepositoryTransaction: Attempting transaction roll-back 2016-09-29 16:34:31,693 ERROR org.apache.sqoop.core.SqoopServer: Server startup failure org.apache.sqoop.common.SqoopException: CONN_0007:Connector registration failed at org.apache.sqoop.connector.ConnectorManager.registerConnectors(ConnectorManager.java:229) at org.apache.sqoop.connector.ConnectorManager.initialize(ConnectorManager.java:186) at org.apache.sqoop.connector.ConnectorManager.initialize(ConnectorManager.java:155) at org.apache.sqoop.core.SqoopServer.initialize(SqoopServer.java:57) at org.apache.sqoop.server.ServerInitializer.contextInitialized(ServerInitializer.java:41) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4210) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4709) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:802) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:779) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:583) at org.apache.catalina.startup.HostConfig.deployWAR(HostConfig.java:944) at org.apache.catalina.startup.HostConfig.deployWARs(HostConfig.java:779) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:505) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1322) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:325) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:142) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1068) at org.apache.catalina.core.StandardHost.start(StandardHost.java:822) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1060) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:463) at org.apache.catalina.core.StandardService.start(StandardService.java:525) at org.apache.catalina.core.StandardServer.start(StandardServer.java:759) at org.apache.catalina.startup.Catalina.start(Catalina.java:595) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414) Caused by: org.apache.sqoop.common.SqoopException: JDBCREPO_0026:Upgrade required but not allowed - Connector: kite-connector at org.apache.sqoop.repository.JdbcRepository$3.doIt(JdbcRepository.java:174) at org.apache.sqoop.repository.JdbcRepository.doWithConnection(JdbcRepository.java:92) at org.apache.sqoop.repository.JdbcRepository.doWithConnection(JdbcRepository.java:63) at org.apache.sqoop.repository.JdbcRepository.registerConnector(JdbcRepository.java:158) at org.apache.sqoop.connector.ConnectorManager.registerConnectors(ConnectorManager.java:212) ... 28 more 2016-09-29 16:34:31,695 ERROR org.apache.sqoop.server.ServerInitializer: Sqoop server failed to start     Any feedback is welcome.   Johann ...
