Subject [jira] [Commented] (HBASE-13780) Default to 700 for HDFS root dir permissions for secure deployments
Date Wed, 27 May 2015 03:13:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14560333#comment-14560333
] 

Jerry He commented on HBASE-13780:
----------------------------------

Looks good.
How does the change affect hbase.data.umask.enable and hbase.data.umask?
Does it still make sense to set hbase.data.umask to 077 under strong security?  Or no need
for strong hbase.data.umask anymore?

> Secure mode deployments should protect the files under HDFS root dir. We should check
and set the root dirs permissions on a kerberos setup so that users does not have to. 
> We have {{hbase.data.umask.enable}} and {{hbase.data.umask}} for data files, but those
are not that useful since we should protect dir listing, and access to WAL files, snapshot
files, etc. 
> See HBASE-13768 which has an integration test for this.
