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

             Summary: Add exponential retry when copyblob is throttled by Azure storage
                 Key: HADOOP-12067
                 URL: https://issues.apache.org/jira/browse/HADOOP-12067
             Project: Hadoop Common
          Issue Type: Bug
          Components: tools
    Affects Versions: 2.7.0
            Reporter: Duo Xu
            Assignee: Duo Xu


HADOOP-11693 passes exponential retry policy to Azure storage SDK when Azure storage throttling
happens. However, when I looked at the source code of Azure storage SDK. Storage exceptions
such as throttling exception are non-retryable.

I would like to add retry in WASB driver instead of depending on Azure storage SDK to make
sure retry happens when Azure storage throttling fires.
