Santhosh G Nayak created HADOOP-14640:
-----------------------------------------

             Summary: Azure: Support affinity for service running on localhost and reuse SPNEGO
hadoop.auth cookie for authorization, SASKey and delegation token generation
                 Key: HADOOP-14640
                 URL: https://issues.apache.org/jira/browse/HADOOP-14640
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/azure
    Affects Versions: 2.9.0
            Reporter: Santhosh G Nayak
            Assignee: Santhosh G Nayak


Currently, {{WasbRemoteCallHelper}} can be configured to talk to comma separated list of URLs
for authorization, SASKey generation and delegation token generation.
To improve the performance, if service runs on the local machine, give it first preference
over the other configured list of URLs. 
Currently, {{WasbRemoteCallHelper}} generates {{hadoop.auth}} cookie for every request by
talking to the remote service, before making actual rest requests.
The proposal is to reuse the {{hadoop.auth}} cookie for subsequent requests from same {{WasbRemoteCallHelper}}
object until its expiry time.
