Andrew Wang commented on HADOOP-9418:
-------------------------------------
bq. what happens when someone changes our "fully resolved" path to include a
symlink
bq. It's safe though if it changes in between, dfs.listPaths will still resolve
it.
Need to correct myself here, it'll error in the case you described. However,
this method is racy throughout; if the path gets deleted, permissions change,
etc, it'll fail to get further listings. Not sure it's worth fixing the symlink
error.
> Add symlink resolution support to DistributedFileSystem
