Alexander Shraer updated ZOOKEEPER-1625:
----------------------------------------
Description:
zkServer.sh is currently looking for "clientPort" entry in the static
configuration file and uses it to contact the server.
With ZOOKEEPER-1411 clientPort is part of the dynamic configuration, and may
appear in the separate dynamic configuration file. The "clientPort" entry may
no longer be in the static config file.
With the proposed patch zkServer.sh first looks in the old (static) config
file, then if clientPort is not there, it figures out the id of the server by
looking at myid file, and then using that id finds the client port in the
dynamic config file.
was:
With ZOOKEEPER-1411 clientPort is part of the dynamic configuration, and may
appear in the separate dynamic configuration file. zkServer.sh is looking for
"clientPort" only in the static configuration file and uses it to contact the
server.
There are several alternatives to fix this:
1. add a parameter to zkServer.sh similarly to the parameter of zkCli.sh (for
example -server 127.0.0.1:2792)
2. Have zkServer.sh first look in the old config file, then if clientPort is
not there, it should figure out the id of the server by looking at myid file,
and then using that id find the client port in the dynamic config file.
3. Always have clientPort in the static config file. If the client port changes
in a reconfiguration, update clientPort in the static config file in addition
to updating the dynamic config file. This would require changes to 1411 and
107, while the scripts would remain the same. This is a bit ugly since it
requires updating the port in two files and breaks the separation of static and
dynamic configs in 1411.
I'd prefer the easiest option - 1, but not sure if there are any implications
on the people using zkServer.sh
