Subject [jira] [Commented] (HDFS-8241) Remove unused Namenode startup option "FINALIZE"
Date Sat, 25 Apr 2015 15:47:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14512569#comment-14512569
] 

Charles Wimmer commented on HDFS-8241:
--------------------------------------

A fatal error would obviously be prefereable to a silent failure.   It is also no longer obvious
when a filesystem requires finalization.

(I'll skip my rant about how HDFS-5138 was probably the cause for me losing blocks on an upgrade
from 2.2 to 2.4.1)
