Xiao Chen commented on HDFS-11188: ---------------------------------- The change and the discussion on more permissive makes sense to me. +1, committing this. > Change min supported DN and NN versions back to 2.x > --------------------------------------------------- > > Key: HDFS-11188 > URL: https://issues.apache.org/jira/browse/HDFS-11188 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: rolling upgrades > Affects Versions: 3.0.0-alpha1 > Reporter: Andrew Wang > Assignee: Andrew Wang > Priority: Critical > Attachments: HDFS-11188.001.patch > > > This is the inverse of HDFS-10398 and HADOOP-13142. Currently, trunk requires > a software DN and NN version of 3.0.0-alpha1. This means we cannot perform a > rolling upgrade from 2.x to 3.x. > The first step towards supporting rolling upgrade is changing these back to a > 2.x version. For reference, branch-2 has these versions set to "2.1.0-beta". -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
