> Key: HADOOP-18959
> URL: https://issues.apache.org/jira/browse/HADOOP-18959
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
>
> Some of the recent changes (HADOOP-18399, HADOOP-18291, HADOOP-18829 etc)
> have added more params for prefetch CachingBlockManager c'tor to process
> read/write block requests. They have added too many params and more are
> likely to be introduced later. We should use builder pattern to pass params.
> This would also help consolidating required prefetch params into one single
> place within S3ACachingInputStream, from scattered locations.
