--------------------------------
Summary: Issues in finalizing rolling upgrade when there is a
layout version change
Key: HDFS-6601
URL: https://issues.apache.org/jira/browse/HDFS-6601
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Kihwal Lee
Assignee: Kihwal Lee
After HDFS-6545, we have noticed a couple of issues.
- The storage dir's VERSION file is not properly updated. This becomes a
problem when there is a layout version change. We can have the finalization do
{{storage.writeAll()}}
- {{OP_ROLLING_UPGRADE_FINALIZE}} cannot be replayed, once the corresponding
{{OP_ROLLING_UPGRADE_START}} is consumed and a new fsimage is created (e.g.
rollback image). On restart, NN terminates complaining it can't finalize
something that it didn't start. We can make NN ignore
{{OP_ROLLING_UPGRADE_FINALIZE}} if no rolling upgrade is in progress.
