Ted Yu commented on HBASE-16060:
--------------------------------
I was reading the code in TableStateManager:
{code}
private void migrateZooKeeper() throws IOException {
if
(this.master.getConfiguration().getBoolean(MIGRATE_TABLE_STATE_FROM_ZK_KEY,
false)) {
return;
}
{code}
It seems the condition above should be the other way around - when migration
flag is false, the method returns early.

> Since table state is migrated to meta instead of zk in 2.0, 1.x clients
> talking to 2.0 cluster cannot access the table state. This causes some weird
> behavior since from a client perspective, {{Admin.isTableEnabled()}} and
> {{Admin.isTableDisabled()}} both return false.
> One option we can do is to add code in 1.x clients so that they can access
> the table state in meta if needed. Otherwise, we can mirror the table state
> in zk (while keeping meta as the source of truth) during 2.x lifecycle so
> that any 1.x client can still work correctly.
