---------------------------------------
Summary: add option to switch to prefetching for given s3a stream
read formats
Key: HADOOP-18791
URL: https://issues.apache.org/jira/browse/HADOOP-18791
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.6
Reporter: Steve Loughran
before switching to prefetching input stream everywhere, add an option to list
which of the fs.option.openfile.read.policy policies to switch too, e.g
fs.s3a.inputstream.prefetch.policies=whole-file, sequential, adaptive
this would leave random and vectored on s3a input stream.
