I am new to apache zookeeper and I read from an article that
Zookeeper manages the entire workflow of starting and stopping various nodes in the Hadoop’s cluster.
If it so, can anyone tell me how..

In HADOOP when u create multiple node cluster ,for co-ordination between data nodes and name node zookeeper is used.
It regularly updates the status of datanodes.
