             Summary: WASB: delete recursive should not fail if a file is 
deleted
                 Key: HADOOP-14769
                 URL: https://issues.apache.org/jira/browse/HADOOP-14769
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/azure
            Reporter: Thomas Marquardt
            Assignee: Thomas Marquardt


FileSystem.delete(Path path) and delete(Path path, boolean recursive) return 
false if the path does not exist.  The WASB implementation of recursive delete 
currently fails if one of the entries is deleted by an external agent while a 
recursive delete is in progress.  For example, if you try to delete all of the 
files in a directory, which can be a very long process, and one of the files 
contained within is deleted by an external agent, the recursive directory 
delete operation will fail if it tries to delete that file and discovers that 
it does not exist.  This is not desirable.  A recursive directory delete 
operation should succeeed if the directory initially exists and when the 
operation completes, the directory and all of its entries do not exist.
