Description

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

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

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:

specialTables = masterServices.listTableNamesByNamespace(NamespaceDescriptor.SYSTEM_NAMESPACE_NAME_STR)
