------------------------------------
Summary: Remove duplicate check
Key: ZOOKEEPER-3904
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3904
Project: ZooKeeper
Issue Type: Improvement
Reporter: Guo Jiwei
ContainerManager#getCandidates:
```
if ((node != null) && node.getChildren().isEmpty()) {
/*
cversion > 0: keep newly created containers from being
deleted
before any children have been added. If you were to create
the
container just before a container cleaning period the
container
would be immediately be deleted.
*/
if (node.stat.getCversion() > 0) {
candidates.add(containerPath);
```
It has already checked the below logic, so no need to do it one more time.
```
if ((node != null) && (node.stat.getCversion() > 0) &&
(node.getChildren().isEmpty())) {
candidates.add(containerPath);
}
```
