[ https://issues.apache.org/jira/browse/HDFS-7121?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Chris Nauroth updated HDFS-7121: Summary: For JournalNode operations that must succeed on all nodes, execute a pre-check to verify that the operation can succeed. (was: For JournalNode operations that must succeed on all nodes, attempt to undo the operation on all nodes if it fails on one node.)
