Steve Loughran commented on HADOOP-19120:
-----------------------------------------
if we move to java11 there's apparently a better one there too. which probably
supports kerberos auth, if that's relevant.
If you look at the s3a code related to connection pooling you'll see some of
the problems to be handled
* explicity discard connections which return errors
* handle TTL of connections in pool
* the problem of *not enough connections in pool* recurrent one this.
* identification of state connections.
You'll need to handle these. Not looked at your PR, but we can link you to the
problems so you know what to do.
> [ABFS]: ApacheHttpClient adaptation as network library
> ------------------------------------------------------
>
> Key: HADOOP-19120
> URL: https://issues.apache.org/jira/browse/HADOOP-19120
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.5.0
> Reporter: Pranav Saxena
> Assignee: Pranav Saxena
> Priority: Major
> Labels: pull-request-available
>
> Apache HttpClient is more feature-rich and flexible and gives application
> more granular control over networking parameter.
> ABFS currently relies on the JDK-net library. This library is managed by
> OpenJDK and has no performance problem. However, it limits the application's
> control over networking, and there are very few APIs and hooks exposed that
> the application can use to get metrics, choose which and when a connection
> should be reused. ApacheHttpClient will give important hooks to fetch
> important metrics and control networking parameters.
