Sean Mackrory commented on HDFS-11096: -------------------------------------- For anyone following this thread, I've come back to this and pushed some updates to the tests at https://github.com/mackrorysd/hadoop-compatibility. * fixes for some idempotence / SSH automation problems that could've popped up before in the rolling upgrade test, and actually validating the sorted data. * [~eddyxu] wrote a little framework for writing tests against mini HDFS clusters of 2 different versions in Python, and a test that you can cp between 2 clusters. I did a bit of refactoring and added tests that check for similar output for most of the "hdfs dfs" commands currently in Hadoop 2. > 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
