------------------------------------

hi [~prasadm]. there exists inconsistent with reading policy file in sentry solr plug-in. This jira is a good example. Because the user configure the parameter sentry.solr.provider.resource=/user/solr/sentry/sentry-provider.ini. The value of resource has no schema. This resource will be used in two places:the constrcuting of LocalGroupResourceAuthorizationProvider and SimpleFileProviderBackend. The SimpleFileProviderBackend will used the configuration given by the SolrAuthBing and it know the resource was put on HDFS. LocalGroupResourceAuthorizationProvider hasn't an chance to get the configuration, because it has no construct function with a configuration parameter. LocalGroupResourceAuthorizationProvider uses LocalFileSystem to find the resource when no schema set, that's why this problem happen.
