HDFS upgrade under HA
Hi,
The layout version is -43 until 2.0.4-alpha, but HDFS-4908 changed layout
version to -45.
so if My test cluster is running hadoop-2.0.4-alpha(-43), which is upgraded
from hadoop-1.0.4, then I want to upgrade using trunk(-45), how to do?
It cannot upgrade under HA, so I can use hadoop-1.0.4 core-site and
hdfs-site, then "start-dfs.sh -upgrade", but standby NN cannot upgrade,
so how to upgrade standby NN under HA?

Layout version can increase (or decrease given it is negative number) by
more than 1, when you upgrade to a new release. So 2.0.4-alpha(-43) can
upgrade to trunk(-45) version.

What is preventing you from upgrading? Please add details on what you are
doing and what issue you are seeing.
