@MB These are INFO messages and can be found in any Properly Working Ambari Server Log as well. There is nothing to worry. This happens because ambari code recursively tries to find few directories for finding the "repoinfo.xml" file and prints the INFO message when it is not found. https://github.com/apache/ambari/blob/release-2.5.0/ambari-server/src/main/java/org/apache/ambari/server/stack/StackDirectory.java#L320-L331 Example: 18 May 2017 09:33:25,118 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=HIVE, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/HIVE/repos 18 May 2017 09:33:25,119 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=RANGER_KMS, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/RANGER_KMS/repos 18 May 2017 09:33:25,121 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=MAHOUT, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/MAHOUT/repos 18 May 2017 09:33:25,122 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=KAFKA, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/KAFKA/repos 18 May 2017 09:33:25,124 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=SPARK, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/SPARK/repos 18 May 2017 09:33:25,126 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=SLIDER, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/SLIDER/repos 18 May 2017 09:33:25,127 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=OOZIE, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/OOZIE/repos 18 May 2017 09:33:25,129 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=ZOOKEEPER, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.5/services/ZOOKEEPER/repos 18 May 2017 09:33:25,295 INFO [main] StackServiceDirectory:116 - No repository information defined for , serviceName=KNOX, repoFolder=/var/lib/ambari-server/resources/stacks/HDP/2.3/services/KNOX/repos . ...
