Here is the small query:
I was going through a tutorial in which i found that Increment generator type should not be used in clustered deployment environment.
Can anybody tell me the reason behind the same?

Because the value is generated by Hibernate rather than the database. If you have multiple JVMs generating ids for the same entity you can't guarantee the value is unique.
