> Knox doesn't read only the service.xml files during startup, but all files in
> the respective dir:
> Check ServiceDefinitionsLoader.java:59
> reference github file:
> [https://github.com/hortonworks/knox/blob/HDP-2.6.4.0-91-tag/gateway-server/src/main/java/org/apache/hadoop/gateway/util/ServiceDefinitionsLoader.java]
> getFileList
> for ( File file : getFileList(servicesDir) ) {
> - Read new and old config files can result in an incorrect based on outdated
> definitions.
> - ServiceDefinitionsLoader.java or getFileList function should be modified
> in order to read only .xml$ files in the directory.
> Workaround.
> =========
> As a workaround by removing the rpmsave files and restarting Knox fix the
> issue.
