[jira] [Commented] (HDFS-16749) RBF:Gets the wrong directory information from Trash
[ https://issues.apache.org/jira/browse/HDFS-16749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17619205#comment-17619205 ]
Xiping Zhang commented on HDFS-16749:
-------------------------------------
{code:java}
//代码占位符 MountTableResolver.java
public List<String> getMountPoints(final String str) throws IOException {
verifyMountTable();
String path = RouterAdmin.normalizeFileSystemPath(str);
// if (isTrashPath(path)) {
// path = subtractTrashCurrentPath(path); // do not need to process the trash path to get the real mount point
// }
readLock.lock();
try {
String from = path;
String to = path + Character.MAX_VALUE;
SortedMap<String, MountTable> subMap = this.tree.subMap(from, to);
return FileSubclusterResolver.getMountPoints(path, subMap.keySet());
} finally {
readLock.unlock();
}
} {code}
