Andy Isaacson created HDFS-4205:
-----------------------------------
Summary: fsck fails with symlinks
Key: HDFS-4205
URL: https://issues.apache.org/jira/browse/HDFS-4205
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs client
Affects Versions: 2.0.2-alpha, 3.0.0
Reporter: Andy Isaacson
I created a symlink using
{code}
...
FileContext fc = FileContext.getFileContext(dst.fs.getUri());
for (PathData src : srcs) {
fc.createSymlink(src.path, dst.path, false);
}
{code}
After doing this to create a symlink {{/foo/too.txt -> /foo/hello.txt}}, I
tried to {{hdfs fsck}} and got the following:
{code}
[adi@host01 ~]$ hdfs fsck /
Connecting to namenode via http://host01:21070
FSCK started by adi (auth:SIMPLE) from /172.29.122.91 for path / at Fri Nov 16
15:59:18 PST 2012
FSCK ended at Fri Nov 16 15:59:18 PST 2012 in 3 milliseconds
hdfs://host01:21020/foo/hello.txt
Fsck on path '/' FAILED
{code}
It's very surprising that an unprivileged user can run code which so easily
causes a fundamental administration tool to fail.
