[jira] [Commented] (CURATOR-408) Handle graceful close of ZookKeeper client waiting for all resources to be released

    [ https://issues.apache.org/jira/browse/CURATOR-408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15996588#comment-15996588 ] 

Enrico Olivelli commented on CURATOR-408:
-----------------------------------------

[~randgalt] 
My initial idea is to add a CuratorZookeeperClient#close(int timeoutMs) method which in turn will call ZooKeeper#close(int).
I will need to add such methods to ConnectionState and HandleHolder, changing HandleHolder#internalClose too
It this is the right direction I will submit a PR soon

Is there any other interesting attach point for the new ZooKeeper#close(int) method ?

> Ths idea is to leverage the new ZooKeeper#close(timeoutMs) method introduced with ZOOKEEPER-2697.
> This new method waits for the internal threads to finish, this way the client is sure that all internal resources handled but low-level ZooKeeper client have been released.
> This is very useful in tests because the user can wait for the test environment to be cleared.
> In some cases you want to return from the 'close' method as soon as possibile. In ZooKeeper a new specific method as been added in order to let the user ask for a specific behaviour.
