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