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) > Remove unused Namenode startup option "FINALIZE" > ------------------------------------------------- > > Key: HDFS-8241 > URL: https://issues.apache.org/jira/browse/HDFS-8241 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Affects Versions: 2.7.0 > Reporter: Brahma Reddy Battula > Assignee: Brahma Reddy Battula > > Command : hdfs namenode -finalize > 15/04/24 22:26:23 INFO namenode.NameNode: createNameNode [-finalize] > *Use of the argument 'FINALIZE' is no longer supported.* To finalize an > upgrade, start the NN and then run `hdfs dfsadmin -finalizeUpgrade' -- This message was sent by Atlassian JIRA (v6.3.4#6332)
