> HDFS-4025 adds support for sychronizing past log segments to JNs that missed them. But,
as pointed out by [~jingzhao], if the segment download happens when an admin tries to rollback,
it might fail ([see comment|https://issues.apache.org/jira/browse/HDFS-4025?focusedCommentId=15850633&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15850633]).
