Subject [jira] [Commented] (HBASE-18948) HBase tags are server side only.
Date Thu, 05 Oct 2017 21:56:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16193800#comment-16193800

Josh Elser commented on HBASE-18948:
------------------------------------

bq. But coprocessors can currently access and set cell Tags. So then the proposed patch is
not accurate.

bq. Edit: I know the security coprocessors defend against the possibility of user submission
of faked security cell tag by stripping them out. Or, I remember writing that code. Again
the current state of the code should be reviewed.

Please see the discussion already on this issue that recommended that the code must be reviewed
to ensure that all CP paths are accurate. There is ambiguity around this area.

> HBase tags are server side only. In the Apache HBase documentation, in section 62.1.1
http://hbase.apache.org/book.html#_implementation_details , I am going to add a sentence to
state explicitly that "Tags are not available for get/set from client operations including
coprocessors".
