Review Comment:
jdk code doesn't expose any enum or constant, even they are using a string:

> ----------------------------------------------------

> Key: HADOOP-18501
> URL: https://issues.apache.org/jira/browse/HADOOP-18501
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.3.4
> Reporter: Pranav Saxena
> Assignee: Pranav Saxena
> Priority: Minor
> Labels: pull-request-available
>
> Error Description:
> For partial read (due to account backend throttling), the ABFS driver retry
> but doesn't add up in the throttling metrics.
> In case of partial read with connection-reset exception, ABFS driver retry
> for the full request and doesn't add up in throttling metrics.
> Mitigation:
> In case of partial read, Abfs Driver should retry for the remaining bytes and
> it should be added in throttling metrics.
