Arshad Mohammad updated ZOOKEEPER-2130:
---------------------------------------
Description:
It is good to have a command which can give complete summary of zookeeper
ensemble. Ensemble summary should give information about who is leader, which
are followers, observers.
Consider a zookeeper cluster with following configurations
server.1=localhost:33230:33235:participant;localhost:33222
server.2=localhost:33231:33236:participant;localhost:33223
server.3=localhost:33232:33237:participant;localhost:33224
server.4=localhost:33233:33238:participant;localhost:33225
server.5=localhost:33234:33239:participant;localhost:33226
When four servers are running and we execute esum(Ensemble Summary Command)
command we should get status of all the servers and their roles
Example:
{quote}
server.1=localhost:33230:33235:participant;localhost:33222
{color:green}FOLLOWING{color}
Client Connections:1
server.2=localhost:33231:33236:participant;localhost:33223
{color:green}FOLLOWING{color}
Client Connections:0
server.3=localhost:33232:33237:participant;localhost:33224 {color:red}NOT
RUNNING{color}
server.4=localhost:33233:33238:participant;localhost:33225
{color:green}FOLLOWING{color}
Client Connections:0
server.5=localhost:33234:33239:participant;localhost:33226
{color:blue}LEADING{color}
