Subject [jira] [Commented] (HBASE-7066) Some HMaster coprocessor exceptions are being swallowed in try catch blocks
Date Wed, 31 Oct 2012 20:31:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13488198#comment-13488198
] 

Francis Liu commented on HBASE-7066:
------------------------------------

Stack, IMHO it really depends on what the coprocessor wants. In the context of security, it'd
be safer to err on the side of caution if the security module is unable to authorize a request,
as this behavior may be exploited by a malicious user.

In general though we probably need a means for the coprocessor to communicate what can and
can't be ignored.
