Maysam Yabandeh commented on HDFS-5175: --------------------------------------- Any update on this patch? Our network infrastructure showed interest in labeling hadoop data traffic, and this jira could have been used for this purpose. I guess other companies must have similar applications that could benefit from this patch. > Provide clients a way to set IP header bits on connections > ---------------------------------------------------------- > > Key: HDFS-5175 > URL: https://issues.apache.org/jira/browse/HDFS-5175 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.0.5-alpha > Reporter: Lohit Vijayarenu > > It would be very helpful if we had ability for clients to set IP headers when > they make socket connections for data transfers. We were looking into setting > up QoS using DSCP bit and saw that there is no easy way to let clients pass > down a specific value when clients make connection to DataNode. > As a quick fix we did something similar to io.file.buffer.size where client > could pass down DSCP integer value and when DFSClient opens a stream, it > could set the value on socket using setTrafficClass > Opening this JIRA to get more inputs from others who have had experience and > might have already thought about this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
