Todd Lipcon commented on HDFS-5089: ----------------------------------- Why does RESERVED_REL_1_3_0 support SNAPSHOT? I haven't seen any discussion about backporting snapshots to branch-1, and I'd be pretty strongly against it. Maybe this should be a discussion on the dev list? > When a LayoutVersion support SNAPSHOT, it must support > FSIMAGE_NAME_OPTIMIZATION. > --------------------------------------------------------------------------------- > > Key: HDFS-5089 > URL: https://issues.apache.org/jira/browse/HDFS-5089 > Project: Hadoop HDFS > Issue Type: Bug > Components: namenode > Reporter: Tsz Wo (Nicholas), SZE > Assignee: Tsz Wo (Nicholas), SZE > Attachments: h5089_20130813.patch > > > The SNAPSHOT layout requires FSIMAGE_NAME_OPTIMIZATION as a prerequisite. > However, RESERVED_REL1_3_0 supports SNAPSHOT but not > FSIMAGE_NAME_OPTIMIZATION. -- This message is automatically generated by JIRA.
