[jira] [Commented] (HBASE-7966) ACL tests fail on trunk (flaky)

["stack (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590153#comment-13590153 ] 

stack commented on HBASE-7966:
------------------------------

I have seen this too.

Should we be throwing out something like HBaseServers' ServerNotRunningYetException until the acl table is in place?

> 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.
