Re: regions unlinked from table
Bryan,
There is a script attached to
https://issues.apache.org/jira/browse/HBASE-4232 , I have used it a couple
of times to add region on filesystem but not in .META.

A sample run goes like this (note you need to provide path to regioninfo):

${HBASE_HOME}/bin/hbase org.jruby.Main addregion.rb
/hbase/mytable/974303001c9100070f54dbc39ebafa59/.regioninfo
