Andrew Purtell commented on HBASE-7966:
---------------------------------------
There might be a couple of things to try for fixing the test:
- Wait for the table to be enabled with a much longer timeout
- Redo the wait for the table to be enabled with a waitFor(..., Predicate)
where the predicate that checks master and RS internal state for the regions
and complains if different from what the admin API gets back via meta scan
The former might work around the flakiness we see on Jenkins but treats a
symptom.
Seems like the later would make it more likely to show a problem rather than
have issues surface indirectly as test setup timeouts.

> I've noticed that these tests fail for me quite frequently:
> {code}
> org.apache.hadoop.hbase.security.access.TestTablePermissions:
> org.apache.hadoop.hbase.exceptions.TableNotFoundException: _acl_
>
> testQualifierAccess(org.apache.hadoop.hbase.security.access.TestAccessControlFilter):
> org.apache.hadoop.hbase.exceptions.TableNotFoundException: _acl_
> {code}
> The root cause seems to be that, the AccessController only creates the table
> in HMaster.postStartMaster(), but before _acl_ is created, master start
> accepting other create table requests, hence race.
