[jira] [Resolved] (HDFS-5618) NameNode: persist ACLs in fsimage.

     [ https://issues.apache.org/jira/browse/HDFS-5618?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chris Nauroth resolved HDFS-5618.
---------------------------------

       Resolution: Fixed
    Fix Version/s: HDFS ACLs (HDFS-4685)
     Hadoop Flags: Reviewed

+1 for the patch.  I went ahead and committed this to the HDFS-4685 branch.  Since we're isolated on a feature branch, we can destabilize {{TestOfflineEditsViewer}} and {{TestOfflineImageViewer}} briefly while we wait for HDFS-5695 to land in trunk.

> Store ACLs in fsimage so that ACLs are retained across NameNode restarts.  This requires encoding and saving the {{AclManager}} state as a new section of the fsimage, located after all existing sections (snapshot manager state, inodes, secret manager state, and cache manager state).
