Sean Mackrory commented on HDFS-11096: -------------------------------------- That's a good idea, [~rchiang]. Adding in some delays between each step should be trivial and would dramatically increase the surface area of the test. Also, regarding the YARN-3583 issue, it was fortunately addressed by YARN-6143. I have marked the JIRAs as related. > Support rolling upgrade between 2.x and 3.x > ------------------------------------------- > > Key: HDFS-11096 > URL: https://issues.apache.org/jira/browse/HDFS-11096 > Project: Hadoop HDFS > Issue Type: Improvement > Components: rolling upgrades > Affects Versions: 3.0.0-alpha1 > Reporter: Andrew Wang > Assignee: Lei (Eddy) Xu > Priority: Blocker > > trunk has a minimum software version of 3.0.0-alpha1. This means we can't > rolling upgrade between branch-2 and trunk. > This is a showstopper for large deployments. Unless there are very compelling > reasons to break compatibility, let's restore the ability to rolling upgrade > to 3.x releases. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
