Hongchao Deng updated ZOOKEEPER-1997:
-------------------------------------
Description:
The current problem is that it goes to standalone mode if there is only one
server in dynamic file.
I understand that it's necessary to keep standalone mode for backward
compatibility. But since dynamic file was introduced in 3.5 it shouldn't jump
to standalone mode in this case.
Something like this test
[testStandaloneQuorum|https://github.com/apache/zookeeper/blob/fa6d21fa8a8acba812237538e4f7172faf969d37/src/java/test/org/apache/zookeeper/test/StandaloneTest.java#L64]
was incorrectly successful before -- the client port was ignored and the
server was responding through the jetty port.
I was trying to require a client port in ZooKeeper-1992. While I am not sure if
this is a good choice, it definitely help check out some assumptions made
before.
I will leave this thread for discussion and propose to disable standalone mode
on booting up from dynamic file.
was:
It seems there is a special standalone mode.
With the coming of reconfig, this doesn't make any sense.
A single server can also be configured later to add more servers.
