question about file glob in hadoop 0.15

[Olga Natkovich]

Hi,
 
According to 0.15 documentation, FileSystem::globPaths supports {ab,cd}
matching. However, when I tried to use it with pattern
/data/mydata/{data1,data2} I got no results even though I could find the
individual files.
 
Any ideas?
 
Thanks,
 
Olga
