-----------------------------------
Summary: Fix Rename API in BasicOzoneFileSystem
Key: HDFS-15035
URL: https://issues.apache.org/jira/browse/HDFS-15035
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Ayush Saxena
Assignee: Ayush Saxena
In the Rename API :
1. This doesn't work if one of the path contains URI and other doesn't.
{code:java}
if (src.equals(dst)) {
return true;
}
{code}
2. This check is suppose to be done only for directories, but is done for Files
too, it can be moved after getting the FileStatus and checking the type.
{code:java}
// Some comments here
public String getFoo()
{
return foo;
}
{code}
3. This too doesn't work (similar to 1.)
{code:java}
if (srcStatus.isDirectory()) {
if (dst.toString().startsWith(src.toString() + OZONE_URI_DELIMITER)) {
LOG.trace("Cannot rename a directory to a subdirectory of self");
return false;
}
{code}
4. Rename is even success if the URI provided is of different FileSystem.
In general HDFS/Other FS shall throw IllegalArgumentException if the path
doesn't belong to the same FS.
