Yan Xu updated MESOS-672:
-------------------------
Description: (was: Web UI redirection does not work for hosts where the
local interface address is not publicly accessible. For example, with EC2 the
redirection will not work.
There are some possible solutions:
(1) Add a new REST endpoint on the master called 'info'. When master A finds
out that master B is the leader it hits master B's '/master/info' endpoint to
get back information about that master including it's (public) hostname.
- This also requires making sure that each master uses it's public hostname
which may possibly require adding a --hostname flag (similar to what we did on
the slave).
- Alternatively, we could update os::hostname to special case EC2, thus
making Mesos work "out of the box" without requiring operators to explicitly
set it to the private hostname.
(2) Add a 'hostname' field to PID and make sure that stringification of the PID
uses the hostname. Then master redirection is done by getting the hostname of
the PID instead of the IP. Note this still requires detecting the public
hostname using mechanisms mentioned in (1).
(3) Store a separate ZNode for the public hostname. Patch from Brenden
Matthews: https://reviews.apache.org/r/11975/
(4) Store a protobuf blob of 'MasterInfo' in ZooKeeper which includes the
hostname field (suggested by Vinod Kone in the above review). We have to deal
with issues with backwards compatibility. When old slaves read the new master's
data, it deserializes the protobuf blob as a PID; when new slaves read the old
master's data, it deserializes the PID as protobuf.
This ticket intends to evaluate these potential solutions and solicit new ideas.
