Summary: File and Directory metadataEquals does incorrect comparisons for Features Key: HDFS-12194 URL: https://issues.apache.org/jira/browse/HDFS-12194 Project: Hadoop HDFS Issue Type: Bug Components: snapshots Affects Versions: 2.8.0 Reporter: Manoj Govindassamy Assignee: Manoj Govindassamy Looks like the metadata comparisons for Files and Directories are doing object reference equality instead of the equals() check. So, a file with the ACL set exactly same as the old one will still flag as changed. INodeFile and SnapshotCopy #metadataEquals() {noformat} @Override public boolean metadataEquals(INodeFileAttributes other) { return other != null && getHeaderLong()== other.getHeaderLong() && getPermissionLong() == other.getPermissionLong() && getAclFeature() == other.getAclFeature() && getXAttrFeature() == other.getXAttrFeature(); } {noformat} INodeDirectory, SnapshotCopy #metadataEquals() {noformat} @Override public boolean metadataEquals(INodeDirectoryAttributes other) { return other != null && getQuotaCounts().equals(other.getQuotaCounts()) && getPermissionLong() == other.getPermissionLong() && getAclFeature() == other.getAclFeature() && getXAttrFeature() == other.getXAttrFeature(); } {noformat} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
