Subject [jira] [Created] (HADOOP-14642) Add support for caching Authorization and SASKeys
Date Tue, 11 Jul 2017 07:53:02 GMT
Sivaguru Sankaridurg created HADOOP-14642:

             Summary: Add support for caching Authorization and SASKeys
                 Key: HADOOP-14642
                 URL: https://issues.apache.org/jira/browse/HADOOP-14642
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/azure
            Reporter: Sivaguru Sankaridurg

TPCDS runs showed performance issues with Secure Clusters.
One of the main issues was identified to be repeated calls to DTS for the same SASKey and
Authorization request.
The performance issue was mitigated to a large extent by introducing caching for saskeys and
authorization requests.
