 _hbase:meta_ (or _hbase:namespace_). To inject one, use the _HBCK2_ tool:

+stop HBCK2 doing a verstion check against the remote master. If the remote master is not up,
+the version check will prompt a 'Master is initializing response' or 'PleaseHoldException'
+and drop the assign attempt. The '-skip' command punts on version check and will land the
+scheduled assign.
 
 The same may happen to the _hbase:namespace_ system table. Look for the
 encoded Region name of the _hbase:namespace_ Region and do similar to
-what we did for _hbase:meta_.
+what we did for _hbase:meta_. In this latter case, the Master actually
+prints out a helpful message that looks like the following:

+To schedule an assign for the hbase:namespace table noted in the above log line, you would do:
+```HBASE_CLASSPATH_PREFIX=./hbase-hbck2-1.0.0-SNAPSHOT.jar hbase org.apache.hbase.HBCK2 -skip assigns 9559cf72b8e81e1291c626a8e781a6ae```
+... passing the encoded name for the namespace region (the encoded name will differ per deploy).
 
 Review comment:
   this is great. I've had to explain this a ton of times.
