> Key: HADOOP-18759
> URL: https://issues.apache.org/jira/browse/HADOOP-18759
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.4
> Reporter: Anuj Modi
> Assignee: Anuj Modi
> Priority: Major
>
> Today when a request fails with connection timeout, it falls back into the
> loop for exponential retry. Unlike Azure Storage, there are no guarantees of
> success on exponentially retried request or recommendations for ideal retry
> policies for Azure network or any other general failures. Faster failure and
> retry might be more beneficial for such generic connection timeout failures.
> This PR introduces a new Linear Retry Policy which will currently be used
> only for Connection Timeout failures.
> Two types of Linear Backoff calculations will be supported:
> # min-backoff starts with 500 ms and with each attempted retry, back-off
> increments double, capped at 30 sec max
> # min-backoff starts with 500 ms and with each attempted retry, back-off
> increments by 1 sec, capped at 30 sec max
