Subject [jira] [Updated] (HDFS-4551) Change WebHDFS buffersize behavior to improve default performance
Date Tue, 05 Mar 2013 03:01:15 GMT

Mark Wagner updated HDFS-4551:

    Attachment: HDFS-4551.1.patch

I've attached a patch which hardcodes the copy buffer size to 4096. This matches the behavior
of hftp and WebHDFS on trunk.

> Currently on 1.X branch, the buffer size used to copy bytes to network defaults to io.file.buffer.size.
This causes performance problems if that buffersize is large.
