--------------------------------------------------------------------
I traced it back to HBASE-8692 which was marked as fixed for 0.94.9 but was
really fixed in .10.
What happened is that HMaster.getHTableDescriptors(List) is now called instead
of HMaster.getHTableDescriptors() in HBaseAdmin, and by design we call this
method for specific tables until they are gone so not getting a HTD is expected.
