Junping Du commented on HDFS-7694: ---------------------------------- Thanks [~cmccabe] for confirmation. I will cherry-pick this patch to branch-2.6 later when build failure (caused by HADOOP-12715) is figured out. > 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 > Fix For: 2.7.0 > > Attachments: HDFS-7694.001.patch, HDFS-7694.002.patch, > HDFS-7694.003.patch, HDFS-7694.004.patch, HDFS-7694.005.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
