             Summary: improve setting of max connections in AWS client
                 Key: HADOOP-13637
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor

things can go badly wrong if the S3A FS creates a thread pool for IO > than the 
number of pooled AWS http connections (set by property MAXIMUM_CONNECTIONS); 
you also need some for any other IO requests coming in.

The max connections property is currently independent of thread pool size, and 
has a default value of 1. 

this is why there is a troubleshooting section in the docs showing the stack 
trace and instructions to fix".

Better: have a dynamic minimum like thread pool size + n, for a value of n to 
be chosen.
