Subject [jira] [Updated] (HDFS-10877) Make RemoteEditLogManifest.committedTxnId optional in Protocol Buffers
Date Thu, 22 Sep 2016 18:46:20 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Wang updated HDFS-10877:
-------------------------------
    Hadoop Flags: Incompatible change
    Release Note: A new protobuf field added to RemoteEditLogManifest was mistakenly marked
as required. This changes the field to optional, preserving compatibility with 2.x releases
but breaking compatibility with 3.0.0-alpha1.
