> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2350
> Project: ZooKeeper
> Issue Type: New Feature
> Components: scripts
> Affects Versions: 3.5.0
> Reporter: Minoru Osuka
> Priority: Minor
> Attachments: ZOOKEEPER-2350.patch, ZOOKEEPER-2350.patch, ZOOKEEPER-2350.patch, ZOOKEEPER-2350.patch

> Starting with 3.5.0, ZooKeeper has already supported a very convenient dynamic reconfiguration. However, the procedure is slightly complicated. So I propose adding a script to build ensemble with ease.
> Usage:
> {noformat}
> $ ./bin/zkEnsemble.sh help
> usage: ./bin/zkEnsemble.sh {start|stop|status} <parameters>
> Commadns:
> start Start a node of ensemble.
> Parameters:
> --seed Specify the IP address and port of an existing ensemble node that required for 2nd and subsequent nodes.
> This is not required for the 1st node. (Example: 127.0.0.1:2181)
> --ip Normally, you do not need to specify because it is automatically detected.
> If it seems the wrong IP address is found automatically, you can over ride the IP address with this option.
> --clientport The port is used to client connections (2181 by default).
> --peerport The port is used to talk to each other (2888 by default).
> If omitted, it will use the minimum port number that is available between 2888 to 3142.
> --electionport The port is used to leader election (3888 by default).
> If omitted, it will use the minimum port number that is available between 3888 to 4142.
> --role The role of node, it can be participant or observer (participant by default).
> --clientip The IP address for client connections (0.0.0.0 by default).
> If omitted, it will use the minimum port number that is available between 2181 to 2435.
> --confdir Specify a base conf directory (/Users/mosuka/git/zookeeper/conf by default).
> --datadir Specify a base data directory (/tmp/zookeeper by default).
> --foreground Start node in foreground.
> stop Stop a node of ensemble.
> Parameters:
> --ip Normally, you do not need to specify because it is automatically detected.
> If it seems the wrong IP address is found automatically, you can over ride the IP address with this option.
> --clientport The port is used to client connections (2181 by default).
> status Show ensemble nodes.
> Parameters:
> --seed Specify the IP address and port of a existing ensemble node (Example: 127.0.0.1:2181).
> help Display this message.
> {noformat}
> Example:
> 1. Start a 1st node of ensemble on host1(192.168.33.11)

> Starting zookeeper ... STARTED
> {noformat}
> 2. Start a 2nd node of ensemble on host2(192.168.33.12).
