-------------------------------
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.
