Subject [jira] [Updated] (HADOOP-9820) RPCv9 wire protocol is insufficient to support multiplexing
Date Thu, 08 Aug 2013 15:41:48 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9820?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daryn Sharp updated HADOOP-9820:
--------------------------------

    Attachment: HADOOP-9820.patch

# Updated get*Stream comments per Sanjay
# Renamed classes for wrapped stream's per Luke
# Removed default buf size per me
#* I was using the RFC max for digest-md5 which is different than gssapi
#* It was the wrong value.  RAW_SEND_BUF is the correct value which is guaranteed to be set.
 Just to be sure, verified in the SASL md5 and krb5 clients.
# Once the SASL auth completes, _only_ SASL wrapped packets are allowed per Sanjay/Luke.

> RPCv9 is intended to allow future support of multiplexing.  This requires all wire messages
to be tagged with a RPC header so a demux can decode and route the messages accordingly.
> RPC ping packets and SASL QOP wrapped data is known to not be tagged with a header.
