Subject [jira] [Commented] (HDFS-6362) InvalidateBlocks is inconsistent in usage of DatanodeUuid and StorageID
Date Fri, 16 May 2014 11:00:22 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13999261#comment-13999261
] 

Arpit Agarwal commented on HDFS-6362:
-------------------------------------

The FindBugs warning looks invalid since the patch does not touch FsAclPermissions.
bq. org.apache.hadoop.hdfs.protocol.FsAclPermission doesn't override org.apache.hadoop.fs.permission.FsPermission.equals(Object)

Also we don't need new tests as per my earlier comment. I will commit this shortly.

> {{InvalidateBlocks}} must consistently use datanodeUuid as the key. e.g. add and remove
functions use datanode UUID and storage ID.
