[jira] [Created] (HADOOP-16618) increase the default number of threads and http connections in S3A

Steve Loughran created HADOOP-16618:
---------------------------------------

             Summary: increase the default number of threads and http connections in S3A
                 Key: HADOOP-16618
                 URL: https://issues.apache.org/jira/browse/HADOOP-16618
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.2.1
            Reporter: Steve Loughran


Enable bigger thread and http pools in the S3A connector, especially now that the transfer manager is doing parallel block transfer, as is rename()

We can make a lot more with parallelism in a single thread, and for applications with multiple worker threads, we need bigger defaults
