Subject [jira] [Commented] (HDFS-8846) Create edit log files with old layout version for upgrade testing

Zhe Zhang commented on HDFS-8846:
---------------------------------

Thanks Ming for the feedback!

I was planning to only add edit log files. But I think creating an entire NN dir structure
with old layout version is a good idea. It could support a broader range of upgrade tests.

> Per discussion under HDFS-8480, we should create some edit log files with old layout
version, to test whether they can be correctly handled in upgrades.
