Subject [jira] [Created] (HBASE-19322) System tables hbase:quota|hbase:acl will be in offline state when cluster startup first time with rsgroup feature

----------------------------------

             Summary: System tables hbase:quota|hbase:acl will be in offline state when cluster
startup first time with rsgroup feature
                 Key: HBASE-19322
                 URL: https://issues.apache.org/jira/browse/HBASE-19322
             Project: HBase
          Issue Type: Bug
          Components: rsgroup
    Affects Versions: 2.0.0-alpha-4
            Reporter: xinxin fan


When cluster start up first time with rsgroup feature, system tables hbase:quota and hbase:acl
 will be in OFFLINE state:

{code:java}
hbase:quota,,1511254877213.0627adae8630c21f4456984713cdffc8. state=OFFLINE, ts=Tue Nov 21
17:03:37 CST 2017 (0s ago), server=localhost,1,1
{code}

It seems that the balancer doesn't know which server to assign the regions,since that  rsgroup
information of the two system tables found to be null.

I read the code and found a issue in rsgroup startup procedure : the rsgroup starts up before
the creating of the two system tables(hbase:quota, hbase:acl), so rsgroupStartupWorker only
adds hbase:meta and hbase:namespace into default group by following function:

{code:java}
specialTables = masterServices.listTableNamesByNamespace(NamespaceDescriptor.SYSTEM_NAMESPACE_NAME_STR)
{code}
