Liang Xie created HDFS-6108: ------------------------------- Summary: make the length of the range in sync_file_range() configurable Key: HDFS-6108 URL: https://issues.apache.org/jira/browse/HDFS-6108 Project: Hadoop HDFS Issue Type: Improvement Components: datanode Affects Versions: 2.3.0, 3.0.0 Reporter: Liang Xie Assignee: Liang Xie
Current codebase has a hard code value for sync_file_range system call, we'd better to make it configurable, since different scenario probably has a different/better value for it. (ps: i found it's 1 * 1024 * 1024 in fb-20 branch) -- This message was sent by Atlassian JIRA (v6.2#6252)
