-------------------------------------
Summary: JN log segment syncing should support HA upgrade
Key: HDFS-11448
URL: https://issues.apache.org/jira/browse/HDFS-11448
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
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
