Arun C Murthy commented on HADOOP-3251:
---------------------------------------
This particular problem seems to stem from the fact that
JobTracker.getFileSystemName returns the value of FileSystem.getName which is
defined by the DistributedFileSystem as:
{code:title=DistributedFileSystem.java|borderStyle=solid}
/** @deprecated */
public String getName() { return uri.getAuthority(); }
{code}
The simple fix for now is to reimplement JobTracker.getFileSystemName as:
{code:title=JobTracker.java|borderStyle=solid}
/**
* Grab the local fs name
*/
public synchronized String getFilesystemName() throws IOException {
if (fs == null) {
throw new IllegalStateException("FileSystem object not available yet");
}
return fs.getUri().toString();
}
{code}
