Subject [jira] [Commented] (HBASE-6222) Add per-KeyValue Security
Date Wed, 20 Jun 2012 17:38:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13397665#comment-13397665
] 

Eric Newton commented on HBASE-6222:
------------------------------------

For clarification, Accumulo does not support negation in the visibility expressions.  "!"
may be reserved for future use, but expressions are limited to terms, "&" or "|" and parens
for precedence.

Visibility expressions are not required: the metadata table does not use them, for example.

The visibility needs to be part of the key in order to have different values at different
visibilities.

@Jonathan - enjoyed your talk @hadoop summit.

> "The  Senate Armed Services Committee version of the fiscal 2013 national defense authorization
act (S. 3254) would require DoD agencies to foreswear the Accumulo NoSQL database after Sept.
30, 2013, unless the DoD CIO certifies that there exists either no viable commercial open
source database with security features comparable to [Accumulo] (such as the HBase or Cassandra
databases)..."
> Not sure what a 'commercial open source database' is, and I'm not sure whats going on
in the article, but tra-la-la'ing, if we had per-KeyValue 'security' like Accumulo's, we might
put ourselves in the running for federal contributions?
