[jira] [Updated] (HADOOP-9060) isSymlink returns false for link to
non-existing file
[ https://issues.apache.org/jira/browse/HADOOP-9060?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Bengtsson updated HADOOP-9060:
-------------------------------------
Description:
This problem showed when trying to use FileUtils.sizeOfDirectory() of a directory that contained a symlink to a file that did not exist. I got the exception:
java.lang.IllegalArgumentException: /tmp/test/link does not exist
at org.apache.commons.io.FileUtils.sizeOf(FileUtils.java:2413)
at org.apache.commons.io.FileUtils.sizeOfDirectory(FileUtils.java:2479)
And /tmp/test/link is here linking to a file that do not exist.
The trace comes from a unit test that looks like:
assertTrue(FileUtils.sizeOfDirectory(new File("/tmp/test/")) > 0);
To me I would expect that either isSymlink() reported true even though the link is to file that do not exist or sizeOfDirectory() should not bail out when encountering non-existing files.
