Hi! I add a custom service and install it with amabri ui, but it hang at the step9.
I check the log find below warning: 28 Mar 2018 05:58:22,229 WARN [ambari-action-scheduler] ActionScheduler:316 - Exception received java.lang.RuntimeException: org.apache.ambari.server.controller.spi.SystemException: Operating System matching redhat7 could not be found at org.apache.ambari.server.actionmanager.ExecutionCommandWrapper.getExecutionCommand(ExecutionCommandWrapper.java:253) at org.apache.ambari.server.actionmanager.ActionScheduler.processInProgressStage(ActionScheduler.java:704) at org.apache.ambari.server.actionmanager.ActionScheduler.doWork(ActionScheduler.java:418) at org.apache.ambari.server.actionmanager.ActionScheduler.run(ActionScheduler.java:310) at java.lang.Thread.run(Thread.java:748) Caused by: org.apache.ambari.server.controller.spi.SystemException: Operating System matching redhat7 could not be found at org.apache.ambari.server.state.stack.upgrade.RepositoryVersionHelper.getOSEntityForHost(RepositoryVersionHelper.java:422) at org.apache.ambari.server.actionmanager.ExecutionCommandWrapper.getExecutionCommand(ExecutionCommandWrapper.java:247) ... 4 more And ui stay 0% process.
