      Description

      I faked an upgrade on a test cluster using our dev data so I had to distcp the data between the two clusters, but after starting up and doing the migration and whatnot the web UI didn't show any table. The reason was in the master's log:

      org.apache.hadoop.hbase.TableExistsException: No descriptor for _distcp_logs_e0ehek
      at org.apache.hadoop.hbase.util.FSTableDescriptors.get(FSTableDescriptors.java:164)
      at org.apache.hadoop.hbase.util.FSTableDescriptors.getAll(FSTableDescriptors.java:182)

      at org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:1326)

      I don't think we need to show a full stack (just a WARN maybe), this shouldn't kill the request (still see tables in the web UI), and why is that a TableExistsException?
