[jira] [Commented] (ZOOKEEPER-279) Allow specialization of quorum config parsing (e.g. variable expansion in zoo.cfg)

["david babits (JIRA)" <ji...@apache.org>]

david babits commented on ZOOKEEPER-279:
----------------------------------------

can somebody confirm whether this feature is available in zookeeper-3.4.5, I can't seem to see it implemented looking at source code in org.apache.zookeeper.server.quorum.QuorumPeerConfig

Thanks.

> We would like to define certain parts of ZooKeeper's configuration using variables that get substituted. For example, we want the ZooKeeper quorum to be able to use a dataDir configured per user. In other words, something like:
> tickTime=2000
> dataDir=/tmp/zookeeper-${user.name}
> clientPort=2181
> initLimit=5
> syncLimit=2
> server.1=zoo1:2888:3888
> server.2=zoo2:2888:3888
> server.3=zoo3:2888:3888
> I think Java already has a system for configuration that allows something like this using Properties?
