Nick Dimiduk reopened HBASE-28842:
----------------------------------
Reopening while we resolve the branch-2.6 compatibility issue flagged on the
2.6.1rc0 VOTE thread,

> TestRequestAttributes should fail when expected
> -----------------------------------------------
>
> Key: HBASE-28842
> URL: https://issues.apache.org/jira/browse/HBASE-28842
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.0.0, 3.0.0
> Reporter: Evelyn Boland
> Assignee: Evelyn Boland
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0-alpha-1, 2.7.0, 3.0.0-beta-2, 2.6.1
>
>
> Problem:
> The tests in the TestRequestAttributes class pass even when they should fail.
> I've included an example of a test that should fail but does not below.
> Fix:
> Throw an IOException in the AttributesCoprocessor when the map of expected
> request attributes does not match the map of given request attributes.
>
> Test:
> We set 2+ request attributes on the Get request but always return 0 request
> attributes from AttributesCoprocessor::getRequestAttributesForRowKey method.
> Yet the test passes even though the map of expected request attributes never
> matches the map of given request attributes.
