[jira] [Commented] (HADOOP-9984) FileSystem#globStatus and
FileSystem#listStatus should resolve symlinks by default
[ https://issues.apache.org/jira/browse/HADOOP-9984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14699137#comment-14699137 ]
Tao Jie commented on HADOOP-9984:
---------------------------------
Since we have flag resolveLinks in globber, will you set resolveLinks to false when we do delete & rename in FSShell?
FsShell delete & rename should operate on symlinks rather than their target, which is reported in HDFS-5021
> FileSystem#globStatus and FileSystem#listStatus should resolve symlinks by default

> During the process of adding symlink support to FileSystem, we realized that many existing HDFS clients would be broken by listStatus and globStatus returning symlinks. One example is applications that assume that !FileStatus#isFile implies that the inode is a directory. As we discussed in HADOOP-9972 and HADOOP-9912, we should default these APIs to returning resolved paths.
