Luke Lu commented on HADOOP-9421: --------------------------------- bq. I also have measured that the NEGOTIATE header is ~61 bytes + length of hostname. On my test cluster, it's 92 bytes. You forgot to count the [protocol overhead|http://sd.wareonearth.com/~phil/net/overhead/], which is between 78 bytes to 114 bytes per packet for TCP over ethernet. > Convert SASL to use ProtoBuf and add lengths for non-blocking processing > ------------------------------------------------------------------------ > > Key: HADOOP-9421 > URL: https://issues.apache.org/jira/browse/HADOOP-9421 > Project: Hadoop Common > Issue Type: Sub-task > Affects Versions: 2.0.3-alpha > Reporter: Sanjay Radia > Assignee: Daryn Sharp > Attachments: HADOOP-9421.patch, HADOOP-9421.patch, HADOOP-9421.patch, > HADOOP-9421.patch, HADOOP-9421-v2-demo.patch > > -- This message is automatically generated by JIRA.
