Subject [jira] [Commented] (HDFS-12823) Backport HDFS-9259 "Make SO_SNDBUF size configurable at DFSClient" to branch-2.7
Date Thu, 16 Nov 2017 21:18:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16255980#comment-16255980

Erik Krogen commented on HDFS-12823:

Hi [~manojg], thanks for taking a look!

I would love to but that method does not exist in branch-2.7. In the 2.7 branch the fields
of {{DFSClient.Conf}} are generally accessed bare; there are 50+ fields and only 4 direct
getter methods.

> Given the pretty significant performance implications of HDFS-9259 (see discussion in
HDFS-10326) when doing transfers across high latency links, it would be helpful to have this
configurability exist in the 2.7 series. 
> Opening a new JIRA since the original HDFS-9259 has been closed for a while and there
are conflicts due to a few classes moving.
