stack commented on HBASE-7966:
------------------------------
This is a kinda ugly one. We need system tables! Can AccessControlFilter retry
when it gets TableNotFoundException?
> ACL tests fail on trunk (flaky)

> Key: HBASE-7966
> URL: https://issues.apache.org/jira/browse/HBASE-7966
> Project: HBase
> Issue Type: Bug
> Components: security
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Fix For: 0.95.0, 0.98.0
>
>
> 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.
