Subject [jira] [Created] (HADOOP-14935) Azure: POSIX permissions are taking effect in access() method even when authorization is enabled

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

             Summary: Azure: POSIX permissions are taking effect in access() method even when
authorization is enabled
                 Key: HADOOP-14935
                 URL: https://issues.apache.org/jira/browse/HADOOP-14935
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/azure
    Affects Versions: 2.9.0
            Reporter: Santhosh G Nayak
            Assignee: Santhosh G Nayak


FileSystem implementation class for azure i.e. {{NativeAzureFileSystem}} does not override
{{access(path,mode)}} method and uses the default implementation from the base class. This
base implementaion uses the POSIX permissions to check if the requested user has access to
given path or not even when authorization is enabled, which is incorrect.
{{NativeAzureFileSystem.access()}} in authorization enabled mode should use the authorization
mechanism provided instead of relying on the POSIX permission ons. So the proposal is to override
{{FileSystem.access()}} method in {{NativeAzureFileSystem}} such that it honors the authorization
mechanism configured in authorization enabled mode and falls back to POSIX permissions otherwise.
