Rajesh Balamohan created HADOOP-14473:
-----------------------------------------

             Summary: Optimize NativeAzureFileSystem::seek for forward seeks
                 Key: HADOOP-14473
                 URL: https://issues.apache.org/jira/browse/HADOOP-14473
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/azure
            Reporter: Rajesh Balamohan
            Priority: Minor


{{NativeAzureFileSystem::seek()}} closes and re-opens the inputstream irrespective of forward/backward seek. It would be beneficial to re-open the stream on backward seek.
