symious opened a new pull request, #3342:
URL: https://github.com/apache/ozone/pull/3342
## What changes were proposed in this pull request?
In NodeImpl, the relation of ancestor is decided as follows:
```
@Override
public boolean isAncestor(Node node) {
return this.getNetworkFullPath().equals(PATH_SEPARATOR_STR) ||
node.getNetworkLocation().startsWith(this.getNetworkFullPath()) ||
node.getNetworkFullPath().equalsIgnoreCase(this.getNetworkFullPath());
```
The corner case is as follows:
```
Node n1: "/rc"
Node n2: "/rc1/dc/1.1.1.1"
```
The result of n1.isAncestor(n2) is false, while in fact n1 is not n2's
ancestor.
