Ted Yu commented on HBASE-19757:
--------------------------------
It seems specialTables was added by commit ca816f07 :
{code}
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 338) List<TableName>
specialTables;
55a1aa1e (Jan Hentschel 2017-01-21 00:38:03 +0100 340) specialTables
= new ArrayList<TableName>(4);
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 341)
specialTables.add(AccessControlLists.ACL_TABLE_NAME);
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 342)
specialTables.add(TableName.META_TABLE_NAME);
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 343)
specialTables.add(TableName.NAMESPACE_TABLE_NAME);
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 344)
specialTables.add(RSGROUP_TABLE_NAME);
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 346) specialTables
=
ca816f07 (Enis Soztutar 2016-03-14 18:28:50 -0700 350) for(TableName
table : specialTables) {
{code}
which was:

> I was testing on an hbase-2 secure cluster against hadoop 3 where some tables
> were created without region server group feature.
> After adding the RSGroupAdminEndpoint and RSGroupBasedLoadBalancer to
> hbase-site, I restarted the whole cluster.
> After the restart, hbase:meta region got stuck in transition (forever).
