Connected to an old server; r-o mode will be unavailable
Hi,
In my log file, I see this warning:
2013-06-18 11:04:15,612 [http-apr-8480-exec-148-SendThread(10.15.9.158:2182)]
WARN ClientCnxnSocket - Connected to an old server; r-o mode will be
unavailable
What does this mean? Is there anything I should be concerned about?
Thanks
BR//Bahman

Ooops, sorry. That is the trace in the client side, I didn't look at it
carefully enough.
Yes it is configurable. See:
http://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html
Experimental Options/Features
Read Only Mode Server

Germán.

No, I am using zookeeper-3.4.5.jar against a server which is 3.3.2. I am
guessing that the server 3.3.2 does not support that mode. correct?
In which use-cases do I need to use "read only mode"? Is this something
configurable?

Hello,
it probably means that you are using the C client, is it?
The C client doesn't seem to support a new functionality called "read only
mode" or "r-o mode" and the server is informing you that it will not be
available.
Nothing to worry about if you don't intend to use that mode, I guess.
Otherwise you are connecting using an old Java API that doesn't suppor that
mode.

Germán.
