Colin Patrick McCabe created HDFS-7694:
------------------------------------------
Summary: FSDataInputStream should support "unbuffer"
Key: HDFS-7694
URL: https://issues.apache.org/jira/browse/HDFS-7694
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 2.7.0
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
For applications that have many open HDFS (or other Hadoop filesystem) files,
it would be useful to have an API to clear readahead buffers and sockets. This
could be added to the existing APIs as an optional interface, in much the same
way as we added setReadahead / setDropBehind / etc.
