Tsz Wo (Nicholas), SZE commented on HADOOP-5119:
------------------------------------------------
Two options to fix FSImage:
1) pass the FSNamesystem as parameter as shown in 5119_20090323.patch.
2) add setFSNamesystem(..) and getFSNamesystem() methods to FSImage.
I originally think that option (1) is a natural fix. But option (2) seems
working better for the newly introduced BackupStorage (see HADOOP-5559). Any
comment?
