-----------------------------------
Summary: SASL negotiation is flawed
Key: HADOOP-8999
URL: https://issues.apache.org/jira/browse/HADOOP-8999
Project: Hadoop Common
Issue Type: Sub-task
Components: ipc
Reporter: Daryn Sharp
Assignee: Daryn Sharp
The RPC protocol used for SASL negotiation is flawed. The server's RPC
response contains the next SASL challenge token, but a SASL server can return
null (I'm done) or a N-many byte challenge. The server currently will not send
a RPC success response to the client if the SASL server returns null, which
causes the client to hang until it times out.
