Akira AJISAKA commented on HDFS-8241:
-------------------------------------
HDFS-5138 removed -finalize option from 2.4.0 (incompatible change), so I'm
thinking this issue can be applied to branch-2 if this issue is to remove the
option from document. The option still exists in the document.

> Remove unused Namenode startup option "FINALIZE"
