     [ https://issues.apache.org/jira/browse/ZOOKEEPER-2697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Enrico Olivelli updated ZOOKEEPER-2697:
---------------------------------------
    Description: 
As seen in ZOOKEEPER-1394 I would like to have the "close"  which waits for all background activities to  finish.
In tests the method "testableWaitForShutdown" is used.

We can add a new ZooKeeper.close(boolean force)  method which will act as testableWaitForShutdown, joining all support threads.

As seen in ZOOKEEPER-1394 I would like to have the "close"  which waits for all background activities to  finish.

In tests the method "testableWaitForShutdown" is used.

My proposal is to add a new boolean configuration options "gracefulClose" (defaults to "false") which adds a logic similar to testableWaitForShutdown at the end of "close" methd.

I would like to add a new configuration property in order to make third party libraries which only call "close" but have a "configurabile" ZooKeeper instance to leverage this new feature
