Kihwal Lee updated HDFS-6601: ----------------------------- Priority: Blocker (was: Major) > 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 > Affects Versions: 2.5.0 > Reporter: Kihwal Lee > Assignee: Kihwal Lee > Priority: Blocker > Attachments: HDFS-6601.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
