> Key: HADOOP-18517
> URL: https://issues.apache.org/jira/browse/HADOOP-18517
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/azure
> Affects Versions: 3.3.4
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> Add an option fs.azure.enable.readahead to allow the abfs readahead to be
> disabled.
> This has been shipping in cloudera releases, because workloads with heavy
> random IO don't always benefit from prefetching.
> Pulling this in to ASF hadoop allows for
> * everyone to experiment with/without prefetching
> * ability to disable prefetching if you have problems with it
