[jira] Commented: (HADOOP-5119) FSEditLog and FSImage should not
use FSNamesystem.getFSNamesystem()
[ https://issues.apache.org/jira/browse/HADOOP-5119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12688949#action_12688949 ]
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?
